1 Chronicles 12:38

⁸“Judah, your brothers will praise you. Your hand will be on the neck of your enemies. Your father’s sons will bow down before you. ⁹Judah is a lion’s cub. From the prey, my son, you have gone up. He stooped down, he crouched as a lion, as a lioness. Who will rouse him up? ¹⁰The scepter will not depart from Judah, nor the ruler’s staff from between his feet, until he comes to whom it belongs. The obedience of the peoples will be to him.

⁶¹“Let your heart therefore be perfect with the LORD our God, to walk in his statutes, and to keep his commandments, as it is today.”

¹²Also the hand of God came on Judah to give them one heart, to do the commandment of the king and of the princes by the LORD’s word.

⁴When Solomon was old, his wives turned away his heart after other gods; and his heart was not perfect with the LORD his God, as the heart of David his father was.

²I will be careful to live a blameless life. When will you come to me? I will walk within my house with a blameless heart.

¹⁷David went out to meet them, and answered them, “If you have come peaceably to me to help me, my heart will be united with you; but if you have come to betray me to my adversaries, since there is no wrong in my hands, may the God of our fathers see this and rebuke it.” ¹⁸Then the Spirit came on Amasai, who was chief of the thirty, and he said, “We are yours, David, and on your side, you son of Jesse. Peace, peace be to you, and peace be to your helpers; for your God helps you.” Then David received them and made them captains of the band.

¹⁹I will give them one heart, and I will put a new spirit within them. I will take the stony heart out of their flesh, and will give them a heart of flesh,

³“Remember now, LORD, I beg you, how I have walked before you in truth and with a perfect heart, and have done that which is good in your sight.” And Hezekiah wept bitterly.

¹Then all the tribes of Israel came to David at Hebron and spoke, saying, “Behold, we are your bone and your flesh. ²In times past, when Saul was king over us, it was you who led Israel out and in. The LORD said to you, ‘You will be shepherd of my people Israel, and you will be prince over Israel.’” ³So all the elders of Israel came to the king to Hebron, and King David made a covenant with them in Hebron before the LORD; and they anointed David king over Israel.

³³Of Zebulun, such as were able to go out in the army, who could set the battle in array with all kinds of instruments of war: fifty thousand who could command and were not of double heart.
