'In that Day' in the Bible

And your little ones, who you said would be a prey, and your sons who in that day had no knowledge between good and evil, they shall go in there. And I will give it to them, and they shall possess it.

Then My anger shall be kindled against them in that day, and I will forsake them. And I will hide My face from them, and they shall be devoured, and many evils and troubles shall befall them, so that they will say in that day, Have not these evils come on us because our God is not among us?

And I will surely hide My face in that day for all the evils which they have done, for they shall turn to other gods.
