˹Moses˺ said, "Your appointment is on the day of the festival when the people assemble at mid-morning."  

Said he, Moses, ‘Your tryst shall be the Day of Adornment — a festive day of theirs on which they adorn themselves and ˹the public˺ assemble — and let the people assemble, ˹let˺ the inhabitants of Egypt gather, at forenoon’, the time for this ˹tryst˺, to observe what will transpire.
