'Holy Covenant' in the Bible

Then shall he return into his land with great property; and his mind shall be against the holy covenant. And he shall take action, and then return to his own land.

For ships from Kittim shall come against him; therefore he shall be intimidated, and shall turn back, and be enraged against the holy covenant, and shall take action. He shall turn back, and show regard to those who forsake the holy covenant.

to show mercy towards our fathers, to remember his holy covenant,
