Esaias,
There are covenants in the Bible not called directly “covenant” but have covenant language. That’s why, for example, there is a “Adamic” covenant.
Also, a covenant created that fulfills an old covenant can effectively replace the old:
Hebrews 8:13 (NKJV) In that He says, “A new [covenant,]” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
Just to be clear, I am not saying that the replacement means nothing is carried over. That’s a related but different topic. Virtually all covenants carry things from the previous ones, because God does not change, and what he cared about before, he still cares about. Mind you, we still practice things from Noahic covenant.
