C. F. Keil and Franz Delitzsch on Psalms 135:19-21

Psa 135:19-21

A call to the praise of Jahve, who is exalted above the gods of the nations, addressed to Israel as a whole, rounds off the Psalm by recurring to its beginning. The threefold call in Psa 115:9-11; Psa 118:2-4, is rendered fourfold here by the introduction of the house of the Levites, and the wishing of a blessing in Psa 134:3 is turned into an ascription of praise. Zion, whence Jahve’s self-attestation, so rich in power and loving-kindness, is spread abroad, is also to be the place whence His glorious attestation by the mouth of men is spread abroad. History has realized this.
