1 Samuel 20:5

So David told him, “Look, tomorrow is the New Moon, and I am supposed to dine with the king. Instead, let me go and hide in the field until the third evening from now.

And David said unto Jonathan, Behold, to morrow is the new moon, and I should not fail to sit with the king at meat: but let me go, that I may hide myself in the field unto the third day at even.
