David
Psalm 68:29ESV·traditional attribution

Because of your temple at Jerusalem kings shall bear gifts to you.

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

Because of thy temple at Jerusalem shall kings bring presents unto thee. The palace of God, which towered above Jerusalem, is prophesied as becoming a wonder to all lands, and when it grew from the tabernacle of David to the temple of Solomon, it was so.

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.
