What are the Covenants in Scripture?
Gal 4:22-24 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. (23) But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. (24) Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
The two covenants are revealed in the life of Abraham. The Old Covenants are promises TO God and the New Covenants is promises BY God.
