Genesi 37:3

Now Israel loved Joseph more than all his children, because he [was] the son of his old age: and he made him a coat of [many] colours.

Ver. 3. Because he was the son of his old age.] The Chaldee Paraphrast renders it morally, Because he was a wise son, in quo ante canos sapientia: such a one as Macarius was, of whom Nicephorus saith, that, for his prudence and gravity while he was yet but a youth, he was surnamed παιδαριογερων, the old stripling. Josephus saith, he was very like his mother Rachel; and therefore his father so loved him.

But Chrysostom saith, better, that it was for his virtuous life, and godly disposition. Goodness is lovely in any; much more in an own child. John was the best beloved disciple, because best conditioned. But otherwise, Cavete, saith Ambrose, ne quos natura coniunxit, paterna gratia dividat. Parents' partiality may breed heart-buruings. Eph 6:4
