John Calvin Commentary Psalms 68:24

"They have seen thy goings, O God, Even the goings of my God, my King, into the sanctuary." — Psalms 68:24 (ASV)

They have seen thy goings, O God! This verse may refer to processions of a warlike kind, or to those made in times of peace by those giving thanks for victory. It is customary for the people of God, on such occasions, to go out and present peace offerings in the temple.

This has led some to interpret the goings of God as the crowds of his people when they proceed to the temple. But I am inclined to think that God himself is here represented as a king leading and marshalling his armies. Accordingly, it is added, in the sanctuary, an expression that aptly alludes to the visible symbol of the Divine presence.

The great reason why God undertakes the guardianship of his people, and goes before them to repel the attacks of the enemy, is that he has promised that he will hear their prayers in the sanctuary. He is therefore described as if he were seen coming out of his holy habitation to conduct his people to victory.

David calls him his King, to divert the attention of the people from himself, and lead them to view a name that belonged to a frail mortal man such as he was, in its higher application to the supreme Head of all. He speaks, it is true, in the name of the people, but not to the exclusion of himself.
