Albert Barnes Commentary Psalms 95:2

"Let us come before his presence with thanksgiving; Let us make a joyful noise unto him with psalms." — Psalms 95:2 (ASV)

Let us come before his presence - Margin, as in Hebrew, “prevent his face.” The word in Hebrew literally means to come before; to anticipate. It is the word commonly rendered “prevent.” See Job 3:12, note; Psalms 17:13, note; Psalms 59:10, note; and 1 Thessalonians 4:15, note.

Here it means to come before, in the sense of “in front of.” Let us stand before His face; that is, in His very presence.

With thanksgiving - Expressing our thanks.

And make a joyful noise unto him - This is the same word that occurs in Psalms 95:1.

With psalms - Songs of praise.
