Adam Clarke on Zechariah 10:12

I will strengthen them in the Lord - I, the God of Israel, will strengthen them in the Lord-Jesus, the Messiah; and thus indeed the Chaldee: I will strengthen them, בימרא דיי bemeymre dayai, in or by the Word of Jehovah, the same personal Word which we so often meet with in the Chaldee paraphrases or Targum.

They shall walk up and down in his name - In the name of the Messiah. Saith the Lord - God speaks here, not of himself, but concerning his Christ. The Jews shall have complete liberty; they shall appear everywhere as a part of the flock of Christ, and no difference be made between them and the converted Gentiles. They shall be all one fold under one Shepherd and Bishop of all souls.
