בְּטַ֣ח אֶל־יְ֭הוָה בְּכָל־לִבֶּ֑ךָ וְאֶל־בִּֽ֝ינָתְךָ֗ אַל־תִּשָּׁעֵֽן׃
Trust in the LORD with all thy heart, And lean not upon thine own understanding.
Rashi on Proverbs
Trust in the Lord and squander your money to seek for yourself a teacher from whom to learn, and do not rely on your understanding.
