Psalms 134:3

“The Lord, that made heaven and earth, bless thee out of Zion.] These are not the words of the priests blessing the people in this form, as some; but rather, as others, the wish of the servants of the Lord, that he would bless him that exhorted them to this service; whether one of the priests, or the captain of the temple, or the psalmist: though, according to Kimchi, and which seems agreeable, they are the words of the psalmist, promising a blessing from the Lord to those that blessed him; as an encouragement to them, to everyone of them, to be constant and diligent in this service. For so it may be rendered, “the Lord shall bless thee”f1802; all blessings come from the Lord, whether…”

“Lord: Psa 124:8, Psa 146:5, Psa 146:6 bless thee: Psa 14:7, Psa 20:2, Psa 110:2, Psa 128:5, Psa 135:21; Rom 11:26 Next: Psalms Chapter 135”

“Calling thus up to the Temple-hill, the church receives from above the benedictory counter-greeting: Jahve bless thee out of Zion (as in Psa 128:5), the Creator of heaven and earth (as in Psa 115:15; Psa 121:2; Psa 124:8).
