Old English hond, hand "hand; side; power, control, possession," from Proto-Germanic *khanduz (cf. Old Saxon, Old Frisian, Dutch, German hand, Old Norse hönd, Gothic handus). The original Old English plural handa was superseded in Middle English by handen, later hands.
Meaning "person who does something with his hands" is from 1580s, hence "hired workman" (1630s) and "sailor in a ship's crew" (1660s). Clock and watch sense is from 1570s. Meaning "round of applause" is from 1838. The linear measure of 4 inches (originally 3) is from 1560s, now used only in giving the height of horses.

First hand, second hand, etc. (mid-15c.) are from the notion of something being passed down from hand to hand. Out of hand (1590s) is opposite of in hand "under control" (c.1200).

To win something hands down (1855) is from horse racing, from a jockey's gesture of letting the reins go loose in an easy victory.

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," etc. 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).
