Wisdom 2:13

13 He professeth to have the knowledge of God: and he calleth himself the child of the Lord.

Wisdom 2:13 In-Context

11 Let our strength be the law of justice: for that which is feeble is found to be nothing worth.
12 Therefore let us lie in wait for the righteous; because he is not for our turn, and he is clean contrary to our doings: he upbraideth us with our offending the law, and objecteth to our infamy the transgressings of our education.
13 He professeth to have the knowledge of God: and he calleth himself the child of the Lord.
14 He was made to reprove our thoughts.
15 He is grievous unto us even to behold: for his life is not like other men's, his ways are of another fashion.
