'In that Day' in the Bible

and Moses sweareth in that day, saying, If not -- the land on which thy foot hath trodden, to thee it is for inheritance, and to thy sons -- to the age, for thou hast been fully after Jehovah my God.

And now, give to me this hill-country, of which Jehovah spake in that day, for thou didst hear in that day, for Anakim are there, and cities, great, fenced; if so be Jehovah is with me, then I have dispossessed them, as Jehovah hath spoken.'
