15:30 I beseech you by the love of the Spirit - That is, by the love which is the genuine fruit of the Spirit. To strive together with me in your prayers - He must pray himself, who would have others strive together with him in prayer. Of all the apostles, St. Paul alone is recorded to desire the prayers of the faithful for himself. And this he generally does in the conclusions of his Epistles; yet not without making a difference. For he speaks in one manner to them whom he treats as his children, with the gravity or even severity of a father, such as Timothy, Titus, the Corinthians, and Galatians; in another, to them whom he treats rather like equals, such as the Romans, Ephesians, Thessalonians, Colossians, Hebrews.

15:31 That I may be delivered - He is thus urgent from a sense of the importance of his life to the church. Otherwise he would have rejoiced "to depart, and to be with Christ." And that my service may be acceptable - In spite of all their prejudices; to the end the Jewish and gentile believers may be knit together in tender love.

15:32 That I may come to you - This refers to the former, With joy - To the latter, part of the preceding verse.

17:24 When they were come to Capernaum - Where our Lord now dwelt.This was the reason why they stayed till he came thither, to ask him for the tribute. Doth not your Master pay tribute? - This was a tribute or payment of a peculiar kind, being half a shekel, (that is, about fifteen pence,) which every master of a familyused to pay yearly to the service of the temple, to buy salt, and little things not otherwise provided for. It seems to have been a voluntary thing, which custom rather than any law had established.

17:25 Jesus prevented him - Just when St. Peter was going to ask him for it. Of their own sons, or of strangers? - That is, such as are not of their own family.

17:26 Then are the sons free - The sense is, This is paid for the use of the house of God. But I am the Son of God. Therefore I am free from any obligation of paying this to my own Father.

17:27 Yet that, we may not offend them - Even those unjust, unreasonable men, who claim what they have no manner of right to: do not contest it with them, bat rather yield to their demand, than violate peace or love. O what would not one of a loving spirit do for peace! Any thing which is not expressly forbidden in the word of God. A piece of money - The original word is a stater, which was in value two shillings and sixpence: just the sum that was wanted. Give for me and thee - Peter had a family of his own: the other apostles were the family of Jesus. How illustrious a degree of knowledge and power did our Lordhere discover! Knowledge, penetrating into this animal, though beneath the waters; and power, in directing this very fish to Peter's hook, though he himself was at a distance! How must this have encouraged both him and his brethren in a firm dependence on Divine Providence.

18:1 Who is the greatest in the kingdom of heaven? - Which of us shall be thy prime minister? They still dreamed of a temporal kingdom.

18:2 And Jesus calling to him a little child - This is supposed to have been the great Ignatius, whom Trajan, the wise, the good Emperor Trajan, condemned to be cast to the wild beasts at Rome! Mar 9:36; Luk 9:47.

18:3 Except ye be converted - The first step toward entering into the kingdom of grace, is to become as little children: lowly in heart, knowing yourselves utterly ignorant and helpless, and hanging wholly on your Father who is in heaven, for a supply of all your wants. We may farther assert, (though it is doubtful whether this text implies so much,) except ye be turned from darkness to light, and from the power of Satan to God:, except ye be entirely, inwardly changed, renewed in the image of God, ye cannot enter into the kingdom of glory. Thus must every man be converted in this life, or he can never enter into life eternal.Ye shall in no wise enter - So far from being great in it. Mat 19:14.
