1 Samuel 20:4-6

Amplified Bible

⁴ Then Jonathan said to David, “Whatever you say, I will do for you.” ⁵ David said to Jonathan, “Behold, tomorrow is the New Moon [observance], and I should sit at the table to eat [the sacrificial meal] with the king; but let me go, so that I may hide myself in the field until the third evening. ⁶ If your father misses me at all, then say, ‘David earnestly asked permission from me to go to Bethlehem, his city, because it is the yearly sacrifice there for the entire family.’
