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, Co2 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, Luk 1:74.
