John Gill Commentary Ezekiel 36:29

"And I will save you from all your uncleannesses: and I will call for the grain, and will multiply it, and lay no famine upon you." — Ezekiel 36:29 (ASV)

And I will also save you from all your uncleannesses
From all their filthy lusts of pride, envy, malice, covetousness, whoredom, blasphemy, and infidelity, to which the Jews are now addicted; but at this time shall be saved from the power and dominion of them by the sanctifying grace of the Spirit; and from the guilt and pollution of them by the blood of Christ sprinkled on them; and this, not from one, or some of them only, but from all of them; all Israel will be saved, and they will be saved from all their sins, (Romans 11:25Romans 11:26) :

and I will call for the corn, and will increase it ;
which shall answer to the call of God, as a servant to his master; and shall spring up out of the earth in great abundance; and which shall grow, and increase, and bring forth much fruit; and yield bread to the eater, and seed to the sower: and which is to be understood, not of corn in a literal sense only, but of corn in a spiritual sense; of all spiritual provisions, the word and ordinances, and especially the corn of wheat, Christ Jesus; who is the sum and substance of the Gospel and his ordinances, and is in them food for the faith of his people; see (Zechariah 9:17) :

and lay no famine upon you ;
neither a famine of bread, or of water; nor of hearing the word of the Lord; but shall have plenty of provisions, both for soul and body; see (Amos 8:11) .
