“The high priest is able to bear with the people patiently and meekly, so as to continue the faithful discharge of his office towards them and for them.
This, as we observed, Moses was not able always to do, as he also complains, ‘Have I conceived all this people? Have I begotten them, that thou shouldest say unto me, Carry them in thy bosom, as a nurse beareth the sucking child?’ (Numbers 11:12)
Yet this is required in a high priest, and that he should no more cast off poor sinners for their ignorance and wanderings than a nursing mother should cast away a sucking child for its crying.
So our apostle, in his imitation of Jesus Christ, affirms that in the church he was ‘gentle among them, even as a nurse cherisheth her children,” (1 Thess. 2:7);—not easy to be provoked, not ready to take offence or cast off the care of him.
So it is said of God, Acts 13:18, that for forty years ἐτροποφόρησε, ‘He bore with the manners of the people in the wilderness;’ or as some read it, ἐτροφοφόρησε, ‘He bore’ or ‘fed them, as a nurse feedeth her child.’
Thus ought it to be with a high priest, and thus is it with Jesus Christ.
He is able, with all meekness and gentleness, with patience and moderation, to bear with the infirmities, sins, and provocations of His people, even as a nursing mother beareth with the weakness of a poor infant.”
