David
Psalm 68:28ESV·traditional attribution

Summon your power, O God, the power, O God, by which you have worked for us.

John Calvin Reformed @genevareformer

PSALM 68 In this psalm it was David’s design to celebrate the victories which, through the blessing of God, he had gained over his enemies; As to the time and occasion of the composition of this psalm, the majority of interpreters refer it to the translation of the ark from the house of Obed-Edom to Mount Zion, and with this every part of it would, no doubt, harmonize.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Thy God hath commanded thy strength. His decree had ordained the nation strong, and his arm had made them so. As a commander in chief, the Lord made the valiant men pass in battle array, and bade them be strong in the day of conflict. This is a very rich though brief sentence, and, whether applied to an individual believer, or to the whole church, it is full of consolation.

Matthew Henry Presbyterian @wholebiblehenry

In these verses we have three things: - I. The gracious promise which God makes of the redemption of his people, and their victory over his and their enemies (Psa 68:22, Psa 68:23): The Lord said, in his own gracious purpose and promise, "I will do great things for my people, as the God of their salvation," Psa 68:20.
