'On that Day' in the Bible

Take of them of the exile, of Heldai, and of Tobijah, and of Jedaiah, - then shalt, thou thyself, enter, on that day, yea thou shalt enter the house of Josiah son of Zephaniah, with them who have come in out of Babylon;

So will Yahweh their God, save them, on that day. yea, as a flock of sheep, his people, - for they shall be like the jewels of a diadem sparkling over his land.

When it was broken, on that day, then did the sheep- merchants who were watching me, know, that, the word of Yahweh, it was.
