Called by Galen "the instrument of instruments." It is the
symbol of human action (Ps. 9:16; Job 9:30; Isa. 1:15; 1 Tim.
2:8). Washing the hands was a symbol of innocence (Ps. 26:6;
73:13; Matt. 27:24), also of sanctification (1 Cor. 6:11; Isa.
51:16; Ps. 24:3, 4). In Ps. 77:2 the correct rendering is, as in
the Revised Version, "My hand was stretched out," etc., instead
of, as in the Authorized Version, "My sore ran in the night,"

The right hand denoted the south, and the left the north (Job
23:9; 1 Sam. 23:19). To give the right hand was a pledge of
fidelity (2 Kings 10:15; Ezra 10:19); also of submission to the
victors (Ezek. 17:18; Jer. 50:15). The right hand was lifted up
in taking an oath (Gen. 14:22, etc.). The hand is frequently
mentioned, particularly the right hand, as a symbol of power and
strength (Ps. 60:5; Isa. 28:2). To kiss the hand is an act of
homage (1 Kings 19:18; Job 31:27), and to pour water on one's
hands is to serve him (2 Kings 3:11). The hand of God is the
symbol of his power: its being upon one denotes favour (Ezra
7:6, 28; Isa. 1:25; Luke 1:66, etc.) or punishment (Ex. 9:3;
Judg. 2:15; Acts 13:11, etc.). A position at the right hand was
regarded as the chief place of honour and power (Ps. 45:9;
80:17; 110:1; Matt. 26:64).
