Charles Ellicott Commentary Leviticus 26:9

"And I will have respect unto you, and make you fruitful, and multiply you, and will establish my covenant with you." — Leviticus 26:9 (ASV)

For I will have respect unto you. —A better rendering is, And I will turn unto you, as it is rendered in the Authorised Version in Ezekiel 46:9, the only other passage where this phrase occurs; that is, He will be merciful to them and bless them. (Compare to 2 Kings 13:23; Psalms 25:16; Psalms 69:17, and others.)

And multiply you, and establish my covenant with you. —That is, by multiplying them as the stars of heaven and the sand of the sea, God fulfills the covenant which He made with their fathers (Genesis 12:2; Genesis 13:16; Genesis 15:5; Genesis 22:17; Exodus 23:26).
