50 27 Instruction in understanding and knowledge I have written in this book, Jesus the son of Sirach, son of Eleazar, of Jerusalem, who out of his heart poured forth wisdom. 50 28 Blessed is he who concerns himself with these things, and he who lays them to heart will become wise. 50 29 For if he does them, he will be strong for all things, for the light of the Lord is his path.
