'Holy Covenant' in the Bible

Then the king of the north will return to his own land with much property. His mind will be set against the holy covenant. He will take action, and then return to his own land.

The ships of Kittim will come against him, leaving him disheartened. He will turn back and direct his indignation against the holy covenant. He will return and honor those who forsake the holy covenant.

He has done this to show mercy to our ancestors, and to remember his holy covenant --
