23 Moreover as for me, far be it from me that I should sin against Yahweh in ceasing to pray for you: but I will instruct you in the good and the right way.

God forbid that I should sin - They had earnestly begged him, 1-Samuel 12:19, to pray to God for them, that they might not die; and he tells them that he should consider himself a sinner, should he cease to be their intercessor.
But I will teach you the good and the right way - I will show you, as long as I am with you, what true religion is; it is the way to happiness and heaven. It is right - there is no crookedness in it; it is good - there is no evil in it.
Moreover, as for me,.... As he had given them reason to believe that God would forgive their sin, by which they had offended him, rejecting him as their King, so he likewise forgave their offence against him in rejecting him as their governor under him, and so neither need fear the Lord nor him with a servile fear; and as God would still be gracious to them, if they abode by his service, so he, Samuel, would do all the good offices for them that lay in his power:
God forbid that I should sin against the Lord, in ceasing to pray for you; for since they had returned to the Lord, and acknowledged their sin, it would have been an evil in him not to pray for them, that they might share in the pardoning grace and mercy of God, and have all good things bestowed upon them they stood in need of; this he judged to be his duty to do, and therefore abhorred the thought of being indifferent to it, negligent of it, or of dropping it:
but I will teach you the good and the right way; would not only pray for them, but instruct them in the way of their duty; a way that was a good one, agreeable to the will and word of God, and in walking in which good things were enjoyed, and which being a good way, must needs be a right way; though Samuel ceased to be a judge and chief magistrate among them, he should not cease to act the part of a prophet to them, both by his prayers and by his instructions.
Samuel then promised the people his constant intercession: "Far be it from me to sin against the Lord, that I should cease to pray for you, and to instruct you in the good and right way," i.e., to work as prophet for your good. "In this he sets a glorious example to all rulers, showing them that they should not be led astray by the ingratitude of their subordinates or subjects, and give up on that account all interest in their welfare, but should rather persevere all the more in their anxiety for them" (Berleb. Bible).
