According to common usage, ‘dedication’ is another word for ‘consecration’. The two words refer to the act of setting apart people or things from the ordinary affairs of life and presenting them to God for his service (Exodus 13:2; Exodus 13:12; Exodus 29:1; Exodus 29:22; Numbers 7:10-11; 1 Samuel 1:11; 1 Samuel 1:24-28; 1 Kings 8:63; 1 Chronicles 26:26; Ezra 6:16-17; for details see CONSECRATION).
The Jewish festival known as the Feast of Dedication celebrated the rededication of the Jewish temple after the defilement by Antiochus Epiphanes in the second century BC (John 10:22; for details see FEASTS).
