1 Chronicles 28:9

Know — So as to love and serve him. Words of knowledge in scripture — use commonly imply affection and practice. Or, acknowledge him, as thy God, by loving and obeying him. Searcheth — If thou dost only put on a profession of religion to please me, or if thy obedience to God be unsincere, thou mayest indeed deceive me, but thou canst not deceive him, for he searcheth the motions of thy heart. Cast thee off — Notwithstanding all his promises to me and to my seed, and that great honour and favour which he hath shewed thee.
