Consecration : 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 (Exodus 13:2,12,15; Numbers 3:12). The Hebrews devoted their fields and cattle, and sometimes the spoils of war, to the Lord (Leviticus 27:28,29). According to the Mosaic law the first-born both of man and beast were consecrated to God.
In the New Testament, Christians are regarded as consecrated to the Lord (1 Peter 2:9).
