What is a “New Moon festival” (1 Samuel 20:5)?
The Hebrew month began with the new moon, and on this day each month the people dedicated the day to the worship of the Lord. Although this day was similar to the Sabbath, there was a greater sense of celebration and joy. There was to be no mourning and no fasting on this day. And the various offerings (Numbers 28:11–15) dedicated to this day were greater in number and quality than those for the Sabbath.
