Shmuel Bais 5:2-4

Orthodox Jewish Bible

² Also in time past, when Sha’ul was melech over us, thou wast he that didst lead out and brought in Yisroel; and Hashem said to thee, Thou shalt feed [like a shepherd] My people Yisroel, and thou shalt become Nagid over Yisroel.

³ So all the zekenim of Yisroel came to HaMelech at Chevron; and Dovid HaMelech cut a Brit with them in Chevron before Hashem; v’yimshechu (and they anointed) Dovid Melech Yisroel.

⁴ Dovid was in age shloshim shanah when he began to reign, and he reigned arba’im shanim.
