Job 16:4
4. heap up—rather, "marshal together (an army of) words against you."
shake . . . head—in mockery; it means nodding, rather than shaking; nodding is not with us, as in the East, a gesture of scorn (Isa 37:22; Jer 18:16; Mt 27:39).Psalms 22:7
7, 8. For the Jews used one of the gestures (Mt 27:39) here mentioned, when taunting Him on the cross, and (Mt 27:43) reproached Him almost in the very, language of this passage.
shoot out—or, "open." the lip—(Compare Ps 35:21).Psalms 22:13
12, 13. His enemies, with the vigor of bulls and rapacity of lions, surround him, eagerly seeking his ruin. The force of both figures is greater without the use of any particle denoting comparison.
Isaiah 50:6
6. smiters—with scourges and with the open hand (Isa 52:14; Mr 14:65). Literally fulfilled (Mt 27:26; 26:27; Lu 18:33). To "pluck the hair" is the highest insult that can be offered an Oriental (2Sa 10:4; La 3:30). "I gave" implies the voluntary nature of His sufferings; His example corresponds to His precept (Mt 5:39).
spitting—To spit in another's presence is an insult in the East, much more on one; most of all in the face (Job 30:10; Mt 27:30; Lu 18:32).
