Therefore we ought to give the more earnest heed
This is an inference from the apostle's discourse in the preceding chapter; since he, by whom God has spoke in these last days, is his Son, who is infinitely above the angels, they being his creatures, and worshippers of him, and ministers to him, and his; therefore the greater regard should be had to the Gospel spoken by him: even to the things which we have heard; which are no other than the truths of the Gospel, which had been preached unto them, and which were heard by the apostles, who had preached them to them; and they had heard them from them, or from Christ himself, and were what their forefathers had desired to hear, and which the carnal ear has not heard; for there is an internal and an external hearing of the Gospel. Now it becomes the hearers of it to give heed, or attend unto it, to beware of that which is pernicious and hurtful, and to regard that which is good and profitable; and this giving heed takes in a close consideration of Gospel truths, a diligent inquiry into them, a valuable esteem of them, a strict adherence to them, and a watchfulness to retain what is heard, and to conform unto it: and this was to be done "more earnestly" than their forefathers had, or than they themselves had; or this may be put for the superlative degree, and signify, that they should give the most earnest heed; for they had the most abundant reason to give heed, since what they heard was not from Moses, and the prophets, to whom they did well to take heed, but from Christ the Son of God, who was greater than they: "lest at any time we should let them slip": and this either respects persons; and so the Vulgate Latin version renders it, "lest we should run out"; and the Syriac version, "lest we should fall"; and the Arabic version, "lest we should fall from honesty": which may intend partial slips and falls, to which the people of God are subject; and which are oftentimes owing to inadvertency to the word; for the Gospel, duly attended to, is a preservative from falling: or it may respect things, even the doctrines of the Gospel, lest we should let them slip out of us, through us, or besides us: the metaphor seems to be taken either from leaking vessels, which let out what is put into them; or to strainers, which let the liquor through, and it falls on the ground, and cannot be gathered up, and so becomes useless; and which is expressive of unprofitable hearing of the word, through inattention, negligence, and forgetfulness, and the irrecoverableness of it, when it is gone: the Gospel may be lost to some that hear it, as to any real benefit and advantage by it; and some who hear the Gospel may be lost and perish; but the grace of the Gospel can never be lost.
