Exodus 16:23

16:23 He said to them, “This is what the Lord has said: ‘Tomorrow is a time of cessation from work, a holy Sabbath to the Lord. Whatever you want to bake, bake today; whatever you want to boil, boil today; whatever is left put aside for yourselves to be kept until morning.’”

Exodus 32:8

32:8 They have quickly turned aside from the way that I commanded them – they have made for themselves a molten calf and have bowed down to it and sacrificed to it and said, ‘These are your gods, O Israel, which brought you up from the land of Egypt.’”
