The lifting up of the hand was a gesture used in speaking, and signifying any weighty thing, Isa 49:22; and particularly in swearing, Ge 14:22; praying, Ps 28:2; and blessing, either of God, Ps 134:2, or of men, as in this place. Paul, speaking of prayer, uses the phrase, "lifting up holy hands;" as also David: "Let the lifting up of my hands be as the evening sacrifice."
