Judges 9:19
If ye then have dealt truly and sincerely with Jerubbaal and with his house this day, then rejoice ye in Abimelech, and let him also rejoice in you:
If ye then have dealt truly and sincerely with Jerubbaal and his house this day,.... If they could in their consciences think and believe they had done well, and acted the faithful and upright part by him and his family, which he left with them to consider of:
then rejoice ye in Abimelech, and let him also rejoice in you; may you be happy in him as a king, and he be happy in you as his subjects, and live peaceably and comfortably together; and this he suggests as a test of their former conduct, that should this alliance between Abimelech and them be attended with happiness, which he could not believe would be the case, then it would seem that they had done a right part by Gideon and his family; but if they should be unhappy together, as he supposed they would, then it would be clear that they had acted a base and disingenuous part by his father's family.
