1 Samuel 20:27-29

On the morrow, which was the second day of the month. Hebrew, "on the morrow of the new moon, the second day." David's absence on the second day made Saul aware that it was no accident, and he demands of Jonathan the reason; whereupon he gives the excuse previously arranged, adding that it was David's brother who had required his attendance. The Septuagint has brothers, being offended at the singular, because Jesse was still alive. But as the festival was not confined to Jesse's household, his brother might very properly be the convener, without usurping his father's place. Let me get away. Literally, "let me escape," "let me get off," a light, half jocose way of speaking adopted by Jonathan, as if the matter were a mere trifle.
