30 And Achiyah took hold of the salmah chadasha that was on him, and tore it into twelve pieces;

31 And he said to Yarov‘am, Take for thee ten pieces; for thus saith Hashem Elohei Yisroel, Hineni, I will tear the mamlachah out of the yad Sh’lomo, and will give to thee asarah hashevatim.

32 (But he shall have hashevet haechad l’ma’an Dovid Avdi, and l’ma’an Yerushalayim, the Ir which I have chosen out of kol shivtei Yisroel;)
