Melachim Bais 10:5-7

Orthodox Jewish Bible

⁵ And he that was over the Bais (Palace), and he that was over the Ir, the zekenim also, and the omenim (guardians [of the royal family]), sent to Yehu, saying, We are thy avadim, and will do all that thou shalt bid us; we will not appoint any melech; do thou that which is tov in thine eyes.

⁶ Then he wrote a sefer (letter) the second time to them, saying, If ye be mine, and if ye will pay heed unto my voice, take ye the rashei anshei bnei adoneichem (the heads of the male children of your master), and come to me to Yizre’el by tomorrow this time. Now the Bnei HaMelech, being seventy persons, were with the Gedolim of the Ir, who were rearing them.

⁷ And it came to pass, when the sefer came to them, that they took the Bnei HaMelech, and slaughtered seventy persons and put their heads in dudim (baskets) and sent him them to Yizre’el.
