Exodus 17:8-13; 24:13; 33:11; Numbers 27:18-23 Scripture gives us no single verse that defines the office of assistant pastor the way it defines the senior pastor or the deacon. Instead, God gives us something instructive, the lives of men who served faithfully alongside another. In the life of Moses, we find two pictures: Aaron and Hur, who held up his hands in battle, and Joshua, who was quietly shaped for leadership over many years. Together, they show us the two halves of this calling, sustaining the man God has placed over you, and being shaped by God in the process. Aaron & Hur: Holding Up the Hands Israel was under attack by Amalek at Rephidim. Moses sent Joshua down into the fight, while he himself climbed a hill overlooking the battle, staff in hand. Exodus 17:11
And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed As long as Moses' hands stayed lifted, Israel had the victory. But Moses was a man, and even a godly man's arms become heavy. Exodus 17:12
But Moses' hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun. What Aaron and Hur Teach Us 1) They held him up, they did not take his place.
Aaron and Hur never reached for the staff. They did not step in to lead the battle or claim any credit for what God did that day. Their whole contribution was simply to keep Moses steady. This is the heart of what an assistant pastor does, he strengthens the man God has placed over him; he does not compete with him. 2) They noticed before they were asked.
Nobody had to tell Aaron and Hur that Moses was struggling. They saw his hands growing heavy, and they acted. Much of faithful ministry is simply paying close enough attention to notice when your leader is growing weary, and stepping in before they ever have to ask. 3) Their work was not glamorous, but it mattered.
No sermon was preached from that hilltop. No miracle was performed by Aaron or Hur. They simply held up arms until the sun went down. So much of this kind of ministry looks exactly like that - quiet, repetitive, tiring, and unnoticed by anyone watching from a distance. But without it, the battle would have been lost. 4) Their faithfulness on the hill won the battle in the valley.
“And Joshua discomfited Amalek and his people with the edge of the sword” (Exodus 17:13). The fighting happened below, but the outcome was decided above, by men who refused to let tired arms decide the day. When those who assist a pastor stay faithful in quiet, unseen ways, the whole church benefits, even those who never once look up at the hill. This picture is not an isolated exception, it is a pattern God builds into how His people are meant to carry burdens. Ecclesiastes 4:9-10
Two are better than one; because they have a good reward for their labour. For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up. And Paul commands the church at Galatia in words that could have been written about that very hillside: Galatians 6:2
Bear ye one another's burdens, and so fulfil the law of Christ. Assistant pastors live this out at the leadership level, but this is not only a pattern for pastors, it is a pattern for the whole church family. Someone near you is carrying heavy arms today. Joshua: The Minister Who Was Being Made Ready Long before Joshua ever led Israel into the promised land, his name shows up quietly, again and again, beside Moses. Scripture gives him a title easy to skim past, but worth considering - he is called Moses' “minister.” Exodus 24:13
And Moses rose up, and his minister Joshua: and Moses went up into the mount of God. One of the most telling verses about Joshua has nothing to do with leadership at all: Exodus 33:11
And the LORD spake unto Moses face to face, as a man speaketh unto his friend. And he turned again into the camp: but his servant Joshua, the son of Nun, a young man, departed not out of the tabernacle. Moses would meet with God and then return to the camp, but Joshua remained behind, alone, in the tabernacle. No one was watching. No assignment required it of him. He simply stayed in the presence of God because he loved being there. This is the kind of hidden faithfulness that shapes a man's heart long before God ever hands him something public to lead. What Joshua's Life Teaches Us 1) He was being shaped, not just used.
Those years beside Moses were not only about getting things done. They were formation. God was quietly building within Joshua the character and dependence on God he would need decades later. If you are serving alongside leadership right now, this season is not wasted. Whether or not you are ever asked to lead publicly, God is building something in you that you will need later, even if you cannot see it yet. 2) Nearness to God matters more than nearness to the platform.
Joshua's greatest qualification was not his skill in battle, it was that he lingered in the tabernacle. Time spent in prayer and in the Word, when no one is watching or applauding, is what makes public ministry bear fruit that lasts. 3) God's timing, not personal ambition, moved him forward.
When it finally came time for Joshua to lead, it did not happen because he pushed for it: Numbers 27:18, 23
And the LORD said unto Moses, Take thee Joshua the son of Nun, a man in whom is the spirit, and lay thine hand upon him... And he laid his hands upon him, and gave him a charge, as the LORD commanded by the hand of Moses. The Lord directed it. Moses commissioned it publicly, before the whole congregation. And the people recognized it. Joshua never appointed himself, and he never campaigned for the role. This remains the pattern God honors today, leadership that comes through divine calling, not simply ambition. 4) Small, hidden faithfulness always comes first.
Joshua served quietly beside Moses for roughly forty years before he ever led Israel across the Jordan. There is no shortcut in Scripture. God is patient, and He proves men in the small places long before He entrusts them with the large ones. When Moses finally laid his hands on Joshua, Scripture tells us exactly what resulted: Deuteronomy 34:9
And Joshua the son of Nun was full of the spirit of wisdom; for Moses had laid his hands upon him: and the children of Israel hearkened unto him, and did as the LORD commanded Moses. This wisdom did not appear in Joshua overnight, it was the fruit of years spent near Moses, watching him pray, watching him lead, watching him fail and repent and trust God again. This is exactly the pattern Paul later instructs Timothy to continue: 2 Timothy 2:2
And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. Faithful men, teaching faithful men, who go on to teach others. This is not a modern leadership strategy, it is simply how God has always grown His church, one faithful life poured into another. A Challenge for All of Us Jesus captured what made Joshua ready long before Israel ever knew his name: Luke 16:10
He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much. An assistant pastor's calling holds both of these truths together. Like Aaron and Hur, he is called to sustain, to notice weariness, to hold up tired hands, and to strengthen the man God has placed over him without ever seeking to replace him. And like Joshua, he is called to be shaped, to remain faithful in hidden, unseen places, trusting that God is building something in him for a purpose only the Lord fully sees. If you are serving in a supporting role right now, in pastoral ministry or anywhere else in this church, don’t be discouraged in the tent or weary in holding up the hands of another. The Lord is not wasting this season. Every one of you who serves faithfully where no one is watching is needed.
