Wisdom 4:6

6 For children begotten of unlawful beds are witnesses of wickedness against their parents in their trial.

Wisdom 4:6 In-Context

4 For though they flourish in branches for a time; yet standing not last, they shall be shaken with the wind, and through the force of winds they shall be rooted out.
5 The imperfect branches shall be broken off, their fruit unprofitable, not ripe to eat, yea, meet for nothing.
6 For children begotten of unlawful beds are witnesses of wickedness against their parents in their trial.
7 But though the righteous be prevented with death, yet shall he be in rest.
8 For honourable age is not that which standeth in length of time, nor that is measured by number of years.
