The same distinguishing blessings on Jacob's remnant, only adopting another figure, are here promised, to show the freedom of God's grace and love to his people. In the former Jacob's remnant is made passive in receiving blessings from the Lord, to denote the Lord's chosen. In this they are shown to be active, in going forth in the Lord's strength, to the Lord's cause. Acting under the name and authority of the lion of the tribe of Judah; the worm Jacob is enabled to thresh the mountains. Isaiah 41:14.
