'On that Day' in the Bible

his dead body shall not hang on the tree, but certainly you shall bury him on that day, for cursed by God [is] one that is [being] hung; so you shall not defile your land that Yahweh your God [is] giving to you [as an] inheritance."

And Moses charged the people on that day, {saying},

And {my anger shall flare up against them} on that day, and I will forsake them, and I will hide my face from them, and they shall become as prey, and disasters and troubles shall find them, and they shall say on that day, '[Is it] not because our God is not in our midst [that] these disasters have found us?'

But I will certainly hide my face on that day, because [of] all of the evil that they did because they turned to other gods.

And Moses wrote this song on that day and taught it [to] the {Israelites}.
