Thy first father hath sinned... — The words have been interpreted: (1) of Adam; (2) of Abraham; (3) of Jacob; (4) of the ancestors of Israel collectively; (5) of this or that high priest individually. (3) fits in best. (See Isaiah 43:28.)
Thy teachers. — Literally, thy interpreters (Job 33:23), or thy mediators. The term is used in 2 Chronicles 32:31 of the “ambassadors “of the king of Babylon, and stands here for the priests and the prophets, who ought officially to have been the expounders of the Divine will.
