not depart from me - never yet fully realized as to the Israelites.
I will not turn away from them ... good - (Isa 30:21). Jehovah compares Himself to a sedulous preceptor following his pupils everywhere to direct their words, gestures.
put my fear in ... hearts ... not depart from me - Both the conversion and perseverance of the saints are the work of God alone, by the operation of the Holy Spirit.
