“From new moon to new moon.” The new moon, the beginning of the month, was celebrated with special sacrifices and offerings (Num. 28:11-15).
“worship me.” Or. “bow down to me.” The Hebrew verb translated “worship” is shachah (#07812 שָׁחָה), and it is the same Hebrew word as is translated “bow down.” The common biblical way of bowing down before people or God was to fall to one’s knees and bow the upper body to the earth. Shachah is translated as both “bow down” and “worship;” traditionally “worship” if God is involved and “bow down” if people are involved, but the verb and action are the same, the act of bowing down is the worship.
