Same as Old Testament
The Wisdom of Jesus is not spectacular original insight as the Christians claim. The same teachings and philosophies are in the Jewish Bible texts and have been taught by Jewish Rabbis for centuries.

1. Matthew 5:3 - Blessed are the poor in spirit for theirs is the kingdom.
Proverbs 29:23 - A man’s pride shall bring him low: but honour shall uphold the humble in spirit.
