'Remnant of Jacob' in the Bible

Then the remnant of JacobShall be among many peoplesLike dew from the Lord,Like showers on the grass [a source of blessing]Which [come suddenly and] do not wait for manNor delay for the sons of men.

The remnant of JacobShall be among the nations,In the midst of many peoplesLike a lion among the beasts of the forest,Like a young lion [suddenly appearing] among the flocks of sheepWhich, if he passes through,Tramples down and tears into pieces [the nations in judgment],And there is no one to rescue.
