'On that Day' in the Bible

And Pharaoh commandeth, on that day, the exactors among the people and its authorities, saying,

But on that day I will separate and set apart the land of Goshen, where My people are living, so that no swarms of insects will be there, so that you may know [without any doubt] and acknowledge that I, the Lord, am in the midst of the earth.

You shall explain this to your son on that day, saying, ‘It is because of what the Lord did for me when I came out of Egypt.’

And Yahweh saved Israel on that day from the hand of Egypt, and Israel saw the Egyptians dead on the shore of the sea.

The LORD told Moses, "Listen very carefully! I'll cause food to rain down for you from heaven, and the people are to go out and gather each day's portion on that day. In this way I'll test them to demonstrate whether or not they'll live according to my instructions.

But the seventh day is a Sabbath to the Lord your God; on that day you are to do no work, you or your son or your daughter, your man-servant or your woman-servant, your cattle or the man from a strange country who is living among you:

So you are to keep the Sabbath as a holy day; and anyone not honouring it will certainly be put to death: whoever does any work on that day will be cut off from his people.

And the sons of Levi do according to the word of Moses, and there fall of the people on that day about three thousand men,

“For six days work may be done, but the seventh day shall be a holy day for you, a Sabbath of complete rest to the Lord; whoever does any kind of work on that day shall be put to death.
