She will do him good, and not evil,.... Or, repay good unto him, give him thanks for all the good things bestowed by him on her; will seek his interest, and promote his honour and glory to the uttermost; all the good works she does, which she is qualified for, and ready to perform, are all done in his name and strength, and with a view to his glory; nor will she do any evil willingly and knowingly against him, against his truths and ordinances; or that is detrimental to his honour, and prejudicial to his interest, 2-Corinthians 13:8;
all the days of her life; through which she desires to serve him in righteousness and true holiness; and to be steadfast and immovable, always abounding in his work, Luke 1:74.

12 ג She doeth good to him, and not evil,
All the days of her life;
or, as Luther translates:
"Sie thut jm liebs und kein leids."
[She does him good, and no harm.]
She is far from ever doing him evil, she does him only good all her life long; her love is not dependent on freaks, it rests on deep moral grounds, and hence derives its power and purity, which remain ever the same. גּמל signifies to accomplish, to perform. To the not assimilated form גּמלתהוּ, cf. יסּרתּוּ, 1b.
