Joshua 1

Even in Moses's last blessings to the tribes of Israel, we see the prophecy and responsibility of Ephraim and Manasseh in the last days -

"...of Joseph he said, Blessed of the LORD be his land, for the precious things of heaven, for the dew, and for the deep that coucheth beneath,
14 And for the precious fruits brought forth by the sun, and for the precious things put forth by the moon,
15 And for the chief things of the ancient mountains, and for the precious things of the lasting hills,
16 And for the precious things of the earth and fulness thereof, and for the good will of him that dwelt in the bush: let the blessing come upon the head of Joseph, and upon the top of the head of him that was separated from his brethren.
17 His glory is like the firstling of his bullock, and his horns are like the horns of unicorns: with them he shall push the people together to the ends of the earth: and they are the ten thousands of Ephraim, and they are the thousands of Manasseh."  (Old Testament | Deuteronomy 33:13 - 17)

Where Moses says "with them he shall push the people together to the ends of the earth".  This is what the hastening of the work is in these latter days, is to push or gather people together throughout the world.

Of those that are called to serve, just as He had done previously, the Lord again counsels Joshua just as he would all that are called  -

"...I will be with thee: I will not fail thee, nor forsake thee.
6 Be strong and of a good courage...Only be thou strong and very courageous, that thou mayest observe to do according to all the law...turn not from it to the right hand or to the left, that thou mayest prosper whithersoever thou goest."  (Old Testament | Joshua 1:5 - 7)

"...Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God is with thee whithersoever thou goest."  (Old Testament | Joshua 1:9)

And then the Lord instructs how his servants may prosper in their callings -

"This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success."  (Old Testament | Joshua 1:8)

As we study the scriptures and ponder them and do and teach them, then we will prosper and have good success.
