The devoting or setting apart of anything to the worship or service of God. The race of Abraham and the tribe of Levi were thus consecrated (Ex. 13:2, 12, 15; Num. 3:12). The Hebrews devoted their fields and cattle, and sometimes the spoils of war, to the Lord (Lev. 27:28, 29). According to the Mosaic law the first-born both of man and beast were consecrated to God.
