Sirach 44:11 In-Context

9 And some there be, which have no memorial; who are perished, as though they had never been; and are become as though they had never been born; and their children after them.
10 But these were merciful men, whose righteousness hath not been forgotten.
11 With their seed shall continually remain a good inheritance, and their children are within the covenant.
12 Their seed standeth fast, and their children for their sakes.
13 Their seed shall remain for ever, and their glory shall not be blotted out.
