David
Psalm 68:30ESV·traditional attribution

Rebuke the beasts that dwell among the reeds, the herd of bulls with the calves of the peoples. Trample underfoot those who lust after tribute; scatter the peoples who delight in war.

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

Rebuke the company of spearmen; or, the beasts of the reeds, as the margin more correctly renders it. Speak to Egypt, let its growing power and jealousy be kept in order, by a word from thee. Israel remembers her old enemy, already plotting the mischief, which would break out under Jeroboam, and begs for a rebuking word from her Omnipotent Friend.

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.
