Ibn Ezra on Exodus 16:19/אבן עזרא על שמות ט״ז:י״ט

אויאמר. הטעם שלא יותירו ממנו לאכלו מחר רק יבטח בשם כי מחר ירד כי אינו מצוה עליו לאכלו כלו רק אם נשאר לו שלא יוכל לאכלו ישליכנו מחוץ לאהלו:

1AND MOSES SAID UNTO THEM: LET NO MAN LEAVE OF IT TILL THE MORNING. Its meaning is, do not leave some of the manna over to eat on the next morning. Rather, trust in the Lord that it will descend on the following day. There was no command to eat the entire omer.⁹⁷ could conceivably be interpreted as a command to consume the entire omer, hence I.E.’s comment. However, that which a person did not consume was to be thrown outside of his tent.
