In the OT to bless means to pronounce the bestowal of benefits such as abundance, fruitfulness, success, prosperity, and longevity of life upon someone or something (Genesis 1:22, 28; 2:3; 17:6; Deuteronomy 28:1-14). In the NT the idea is to praise or speak well of someone, and when God blesses man it also includes provision of certain benefits. Man is able to bless God through worship, thanksgiving, and praise as a response to prior blessing from God (Genesis 24:48; 1 Kings 10:9; Job 1:20-21; Psalms 26:12; 96:2; 103:1-2, 20-22; Nehemiah 9:5; Luke 1:68; 24:53; 1 Corinthians 14:16). To some extent, men can bless or be a blessing to others (Genesis 12:2-3; 24:60; 27:4; 1 Kings 8:66; Luke 6:28; 2 Corinthians 13:14; 1 Timothy 1:2), but God is still the ultimate source of such blessing (Genesis 12:1-3; Deuteronomy 15:14; 2 Samuel 6:18; 2 Corinthians 1:3-4). The term "blessed" is used to describe God Himself or human recipients of benefits, especially from God (Genesis 14:19-20; 24:31; 26:29; Numbers 22:6; 24:9; Deuteronomy 28:1-14; 2 Samuel 6:11-12; 1 Kings 10:8; Ezra 7:27; Psalms 28:6; Daniel 3:28; Romans 1:25; 1 Timothy 6:15). The term "blessing" refers to specific benefits either pronounced or actually bestowed by a superior acting as benefactor (Genesis 27:1-41; 48:20; Exodus 32:29; Deuteronomy 16:17; 2 Samuel 7:29; Psalms 133:3; Ezekiel 34:26; Ephesians 1:3; 1 Peter 3:9). While God's blessing in both the OT and NT includes physical and spiritual benefits (Genesis 24:1; 26:12-13; Deuteronomy 28:1-14; 1 Chronicles 4:10; Psalms 103:1-6; Matthew 6:33; Philippians 4:19; Colossians 1:12-14; 3 John 2), the NT places greater emphasis upon spiritual blessings (Acts 3:26; Galatians 3:8-9, 14; Ephesians 1:3).
