What does Psalm 90:16 mean?

Moses asks the Lord to show favors and power to His people, but not only to them but also to their children. His prayer is similar to that of David. In Psalm 86:17 David prayed, "Show me a sign of your favor, that those who hate me may see and be put to shame because you, LORD, have helped me and comforted me." Moses' request in Psalm 90:16 ascended from a humble heart. He referred to himself and the people he led through the wilderness as the Lord's servants. It is of the utmost importance to remember when we pray that God is not under our command, but we are absolutely subject to Him. David exhibited a humble heart when he prayed in Psalm 35:13: "I wore sackcloth: I afflicted myself with fasting; I prayed with head bowed on my chest."

When Isaiah received a vision of the Lord high and lifted up, he cried out humbly, "Woe is me! For I am lost; for I am a man of unclean lips," and he made himself available to serve the Lord (Isaiah 6:1, 5, 8). We must be careful to avoid arrogance or entitlement when we make requests to the Lord, but we can ask for His favor as Moses did.
