And their heart they have made adamant, Against hearing the law, and the words, That Jehovah of Hosts sent by His Spirit, By the hand of the former prophets, And their is great wrath from Jehovah of Hosts.

don't plot evil in your heart against a neighbor, and don't tolerate false testimonies, because I hate all these things,' declares the LORD."

And they of Ephraim shall be like a mighty man, and their heart shall rejoice as through wine: yea, their children shall see it, and be glad; their heart shall rejoice in the LORD.

And the governors of Judah shall say in their heart, The inhabitants of Jerusalem shall be my strength in the LORD of hosts their God.
