Charles Ellicott Commentary Psalms 134

All you servants: We learn from 1 Chronicles 9:33 that there were Levites whose duties brought them to the Temple by night. Moreover, the word ‘âmad, “stand,” is the customary word for sacerdotal service (Deuteronomy 10:8; Deuteronomy 18:7; 1 Chronicles 23:30, etc.).

Lift up your hands (see Note, Psalms 28:2) (in) the sanctuary.—The usual meaning would be to the sanctuary (see reference above), but since the servants of Jehovah are here addressed as standing in the sanctuary, this direction seems unreasonable. Render, therefore, in holiness, and compare lifting up holy hands (1 Timothy 2:8).

Made heaven and earth. —For this style, as is frequent in this group of psalms, see Psalms 121:2.
