Charles Ellicott Commentary Psalms 109:1

"Hold not thy peace, O God of my praise;" — Psalms 109:1 (ASV)

God of my praise. —That is, God to whom as covenant God it was a privilege to make tehillah (praise). (See Deuteronomy 10:20-21, where Jehovah is said to be the praise of those who swear by His name. Compare also Psalms 106:2-3 and Psalms 33:1.)

Perhaps “God of my glory or boast” would more closely convey the force of the original. The psalmist prays that Jehovah’s silence may not make his confident glorifying in the covenant promises vain.
