Charles Spurgeon Commentary Ezekiel 33:7

"So thou, son of man, I have set thee a watchman unto the house of Israel; therefore hear the word at my mouth, and give them warning from me." — Ezekiel 33:7 (ASV)

So you, O son of man, I have set you a watchman to the house of Israel;

It is not merely the people who took a man from their regions and set him as their watchman; but, I have set you. Oh, the solemn ordination of a true servant of Christ! It is not by the laying on of human hands, nor by a pretended descent from the apostles; it is a call from God.

Therefore you shall hear the word at my mouth, and warn them from me.

That is the way to preach: to get the sermon from the mouth of God, and then to speak it as from the mouth of God. Dear teachers, wait upon God for what you are to teach; take it warm with love from the very mouth of God, and then speak it for God from your own mouth. Good will surely come of such teaching as that.
