Arakhin 15B

״אל תצאו״ ויצאו, ״אל תותירו״ ויותירו.

Do not go out, as indicated in the verse: “And Moses said: Eat that today; for today is a Sabbath for YHWH; today you will not find it in the field” (Exodus 16:25). But nevertheless there were people who went out to look for manna, as it is written: “And it came to pass on the 7th day that some of the people went out to gather, and they found none” (Exodus 16:27). The verse also states: “And Moses said to them: Let no man leave any of it until the morning” (Exodus 16:19), and there were people who left it until morning, as it states: “But they did not listen to Moses; and some of them left of it until the morning, and it bred worms, and rotted; and Moses was angry with them” (Exodus 16:20).

שנים בשליו [בשליו] ⁠— ראשון ובשליו שני. בשליו ראשון ⁠— ״בשבתכם על סיר הבשר״.

The Talmud continues its elucidation of the baraita: There were two trials relating to the quail, one was on the first occasion when the quail appeared, and the other on the second occasion the quail appeared. The Talmud clarifies: The trial of the first quail is described in the verse: “And the children of Israel said to them: Would that we had died by the hand of YHWH in the land of Egypt, when we sat by the meat pots, when we ate bread to the full; for you have brought us into this wilderness, to kill this whole assembly with hunger” (Exodus 16:3). Immediately afterward the quail arrived, as the verse states: “And it came to pass in the evening, that the quail came up, and covered the camp; and in the morning there was a layer of dew round about the camp” (Exodus 16:13).
