'On that Day' in the Bible

So he removed, on that day, the he-goats that were striped and spotted and all the she-goats that were speckled and spotted, every one that had white in it, and every dark-coloured one among the young sheep, - and delivered then into the hand of his sons;

And he blessed them on that day, saying - In thee, let Israel bless himself saying, God set thee as Ephraim, and as Manasseh! So he set Ephraim before Manasseh.
