Shmuel Alef 20:4-6

Orthodox Jewish Bible

⁴ Then said Yonatan unto Dovid, Whatsoever thy nefesh saith, I will even do it for thee.

⁵ And Dovid said unto Yonatan, Hinei, makhar (tomorrow) is Rosh Chodesh, and I should not fail to sit with HaMelech for tish; but let me go, that I may hide myself in the sadeh unto the erev hashlishit.

⁶ If avicha at all miss me, then say, Dovid earnestly asked leave of me that he might run to Beit-Lechem his town; for there is a zevach hayamim there for kol mishpakhat.
