2 Kings 10:6-8

Young's Literal Translation

⁶ And he writeth unto them a letter a second time, saying, `If ye [are] for me, and to my voice are hearkening, take the heads of the men -- the sons of your lord, and come unto me about this time to-morrow, to Jezreel;' and the sons of the king [are] seventy men, with the great ones of the city those bringing them up.

⁷ And it cometh to pass, at the coming in of the letter unto them, that they take the sons of the king, and slaughter seventy men, and put their heads in baskets, and send unto him to Jezreel,

⁸ and the messenger cometh in, and declareth to him, saying, `They have brought in the heads of the sons of the king,' and he saith, `Make them two heaps at the opening of the gate till the morning.'
