The harvest was a major event on the yearly calendar of Israel’s agrarian society (Lev. 25:11; Judg. 15:1; Ruth 1:22; 2 Sam. 21:9–10). Life was dependent on the harvest. As a result, God set certain rules with respect to the harvest to help the Israelites keep proper priorities. Every seven years and every fiftieth year, the people were to give the land a rest (Exod. 23:10; Lev. 25:20–22). The people were to rest on the Sabbath, even during the harvesttime (Exod. 34:21). Some portions of crops were to be left in the field so that the poor might have food (Lev. 19:9; 23:22; Deut. 24:21). The people were to acknowledge God as the source of the harvest by offering the first of the produce (Lev. 23:10). Celebrating the harvest was commanded (Exod. 23:16; Deut. 16:15; Isa. 9:3). Planning for the harvest was a mark of wisdom (Prov. 6:8; 10:5; 20:4). Even as a good harvest was the blessing of God (Ps. 67:6; Isa. 62:9), so a bad harvest was a curse from God and the plight of a fool (1 Sam. 12:17; Job 5:5; Prov. 26:1; Isa. 18:4–5; Jer. 8:13, 20; Joel 3:12; Mic. 6:15). Failure to acknowledge God for the harvest was a sin (Jer. 5:24).
The harvest is often used in Scripture as an analogy. The prophets talk about the negative harvest of idolatry (Isa. 17:11). Israel is called the firstfruits of God’s harvest (Jer. 2:3). Hosea uses the idea of harvest to indicate that God’s people have a future (Hos. 6:11). In the Gospels, the harvest is used as an analogy for those needing to hear the good news (Matt. 9:37–38), for the end times (Matt. 13:24–30; Rev. 14:15), and for a lesson about unfaithful leadership (Matt. 21:33–46; 25:24). In the remainder of the NT, the harvest analogy usually refers to Christian growth and salvation (Rom. 1:13; 1 Cor. 9:10–11; 2 Cor. 9:10; Gal. 6:9; Heb. 12:11; James 3:18).
