The LORD doth build up Jerusalem: he gathereth together the outcasts of Israel.
Ver. 2. The Lord doth build up Jerusalem] He is the only architect of his Church. He layeth the foundation of it in election (saith a good expositor), and buildeth it progressively by faith and sanctification; and finisheth his work of grace and his people's happiness in glorification.
He gathereth together the outcasts of Israel] He will surely bring home his banished; yea, because they called thee an outcast, saying, This is Zion, whom no man seeketh after, therefore I will restore health unto thee, &c., Jeremiah 30:17. Qui nil sperare potest, desperet nihil.
