INTRODUCTION TO PSALM 134 A Song of degrees. This is the last of the psalms called "songs of degrees"; of which See Gill on Psa 120:1, title. It is thought to be written by David, either when he brought the ark to Zion, Sa2 6:17; or rather when he numbered the Levites, and appointed them their service, Ch1 23:26. So the Syriac inscription, ""a psalm" of David, concerning the priests, whom he appointed to wait on the ministry of the Lord in the nights; but, spiritually, an instruction of life.'' Aben Ezra connects it with the preceding psalm, "as the dew of Hermon ye shall be that bless; behold, therefore, ye are bound to bless the Lord?''.
