"Consecrate" means to dedicate or "sanctify" a person or thing to a "sacred" or "hallowed" purpose in the service and worship of God. Such a person or thing may be called "holy." "Consecrated" first appears at Ex.13:2; also see 22:31; 29:1,2,19-21,27,31-34; and Num.18:15-20, all regarding food.
"Sanctified" first appears at Ex.29:43; regarding food, see Lev.22:16.
"Sacred" first shows up at Ex.30:25; regarding food, see Deut.26:13.
"Hallowed" first shows up at Gen.2:3; regarding food, Num.18:25-32, esp. verse 29.
"Holy" first appears at Ex.3:5; regarding food, see Ex.29:33,34.
These first appearances, etc., are based on the RSV; other translations may exchange synonyms for them.

The tabernacle had its holy and most holy rooms--the most holy room contained the ark over which was God's presence. Offerings could be holy or most holy (Lev.21:22; 27: 26,28; Num.18:9). Most holy offerings included sin, guilt, and certain grain offerings, and clean firstborn animals. Such firstborns were among "devoted" things which were either to be killed for God (Lev.27:29), used by priests
