David said to Jonathan, “Behold, tomorrow is the new moon, and I should not fail to dine with the king; but let me go, that I may hide myself in the field to the third day at evening. Bible

“the new moon.” Each new moon, the start of each month, was dedicated to God by special sacrifices and blowing of trumpets (see commentary on Num. 28:11).
