'Holy Covenant' in the Bible

Then shall he return into his land with great substance; and his heart [shall be] against the holy covenant; and he shall do [his pleasure], and return to his own land.

For ships of Kittim shall come against him; therefore he shall be grieved, and shall return, and have indignation against the holy covenant, and shall do [his pleasure]: he shall even return, and have regard to those who forsake the holy covenant.
