* his hand.  or, as the Greek has it, "his hands."
   Menachem gives reason why it is written hand, to signify the
   right hand, because that was lifted up higher than the left.
   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."
