Bless

(1.) God blesses his people when he bestows on them some gift
temporal or spiritual (Gen. 1:22; 24:35; Job 42:12; Ps. 45:2;
104:24, 35).

(2.) We bless God when we thank him for his mercies (Ps.
103:1, 2; 145:1, 2).

(3.) A man blesses himself when he invokes God's blessing
(Isa. 65:16), or rejoices in God's goodness to him (Deut. 29:19;
Ps. 49:18).

(4.) One blesses another when he expresses good wishes or
offers prayer to God for his welfare (Gen. 24:60; 31:55; 1 Sam.
2:20). Sometimes blessings were uttered under divine
inspiration, as in the case of Noah, Isaac, Jacob, and Moses
(Gen. 9:26, 27; 27:28, 29, 40; 48:15-20; 49:1-28; Deut. 33). The
priests were divinely authorized to bless the people (Deut.
10:8; Num. 6:22-27). We have many examples of apostolic
benediction (2 Cor. 13:14; Eph. 6:23, 24; 2 Thess. 3:16, 18;
Heb. 13:20, 21; 1 Pet. 5:10, 11).

(5.) Among the Jews in their thank-offerings the master of the
feast took a cup of wine in his hand, and after having blessed
God for it and for other mercies then enjoyed, handed it to his
guests, who all partook of it. Ps. 116:13 refers to this custom.
It is also alluded to in 1 Cor. 10:16, where the apostle speaks
of the "cup of blessing."
