Verses with the word heir in the Apocrypha (3 verses):

Tobit 3:15
And that I never polluted my name, nor the name of my father, in the land of my captivity: I am the only daughter of my father, neither hath he any child to be his heir, neither any near kinsman, nor any son of his alive, to whom I may keep myself for a wife: my seven husbands are already dead; and why should I live? but if it please not thee that I should die, command some regard to be had of me, and pity taken of me, that I hear no more reproach.

Sirach 22:23
Be faithful to thy neighbour in his poverty, that thou mayest rejoice in his prosperity: abide stedfast unto him in the time of his trouble, that thou mayest be heir with him in his heritage: for a mean estate is not always to be contemned: nor the rich that is foolish to be had in admiration.

Sirach 23:22
Thus shall it go also with the wife that leaveth her husband, and bringeth in an heir by another.
