Charles Ellicott Commentary Deuteronomy 23:5

"Nevertheless Jehovah thy God would not hearken unto Balaam; but Jehovah thy God turned the curse into a blessing unto thee, because Jehovah thy God loved thee." — Deuteronomy 23:5 (ASV)

Because the Lord thy God loved thee. —The contrast between what He says to Israel in this book and what He said by Balaam is very striking. (See on Deuteronomy 31:16.)
