Acts 28:26

Saying, go unto this people, and say
A message sent in wrath and judgment to the people of Israel, rejected from being the people of God, a "lo ammi" being written upon them; and therefore God does not call them "his", but "this" people: and this message was sent by an evangelical prophet, who foretold, in the clearest manner, the Messiah's incarnation, and birth of a virgin, the work he was to do, the sufferings he should undergo, and the glory that should follow; and that after he had seen in a vision the glory of the King Messiah, the perfections of deity filling the temple of his human nature, him exalted on a throne, and attended and worshipped by angels; after he had had such a view of his beauty and excellency, that laid him low in his own sight, and humbled him under a sense of his own impurity and unworthiness; and after he had had a comfortable discovery and application of pardoning grace; and after he had expressed such a readiness and willingness to go on the Lord's errand: which one might have thought would have been of a different nature; and that he would have been sent, and have been made useful, to set forth the glories and excellencies of Christ's person, office, and grace, he had had such a view of; and to preach the comfortable doctrine of pardoning grace to men, which he had just now such a gracious experience of; but on the contrary, he is bid to say,

hearing ye shall hear;
with bodily ears, the Gospel preached by the Messiah and his apostles:

and shall not understand,
spiritually and experimentally, what they heard: to have an opportunity of hearing the Gospel, is a great blessing; seeing it is good news, glad tidings of good things, a joyful sound, and the voice of Christ himself; it is a distinguishing favour, and what all men at all times have not; when it is attended with a divine energy, the Spirit of God is received through it, regeneration, quickening and sanctifying grace are by it; faith comes by hearing it, and Christ is found under the ministration of it; and, generally speaking, the understanding and knowledge of divine things, are by means of it: men are naturally without the understanding of spiritual things, and where the Gospel is not, they remain so; the ministers of the Gospel, and the word preached by them, are the means of leading men into a spiritual understanding of things, though only as, and when attended with the Spirit of God, who is a Spirit of wisdom and revelation, in the knowledge of Christ: and a special mercy it is when persons, whilst hearing the word, understand what they hear, and can distinguish truth from error; and approve of the truth, receive the love of it, feel the power, and taste the sweetness of it; find it and eat it, believe, embrace, and profess it, and bring forth fruits worthy of it: but on the contrary, when it is heard and not understood, it is an awful dispensation; for hence either they content themselves with bare hearing, and depend upon it for salvation; or they despise and speak evil of what they do not understand; and so their hearing, instead of being a blessing, is an aggravation of their condemnation:

and seeing ye shall see:
miracles wrought:

and not perceive;
them to be proofs of the things, for which they are wrought: so Jarchi expounds those words,

``ye shall see the wonders, or miracles I have done for you, and shall not set your hearts to know me''
