Exodus 16:12

‘And you shall keep it until the fourteenth day of the same month, then the whole assembly of the congregation of Israel shall slaughter it at twilight.

and in the morning you will see the glory of Yahweh, for He hears your grumblings against Yahweh; and what are we, that you grumble against us?”

‘For I am Yahweh your God. Therefore, set yourselves apart as holy and be holy, for I am holy. And you shall not make yourselves unclean with any of the swarming things that move on the earth.

They asked, and He brought quail, And He satisfied them with the bread of heaven.
