Shemot 16:18-20

Orthodox Jewish Bible

¹⁸ And when they did measure it by the omer, he that gathered much had nothing extra, and he that gathered little had no lack; they gathered every man according to his eating [need].

¹⁹ And Moshe said, Let no ish leave of it until boker.

²⁰ Notwithstanding, they paid heed not unto Moshe; but some left part of it until boker, and [the leftovers] bred tola’im (worms), and stank; and Moshe was angry with them.
