Matthew 5:19

Whosoever therefore shall break--rather, "dissolve," "annul," or make "invalid." one of these least commandments--an expression equivalent to "one of the least of these commandments." and shall teach men so--referring to the Pharisees and their teaching, as is plain from Mat 5:20, but of course embracing all similar schools and teaching in the Christian Church. he shall be called the least in the kingdom of heaven--As the thing spoken of is not the practical breaking, or disobeying, of the law, but annulling or enervating its obligation by a vicious system of interpretation, and teaching others to do the same; so the thing threatened is not exclusion from heaven, and still less the lowest place in it, but a degraded and contemptuous position in the present stage of the kingdom of God. In other words, they shall be reduced by the retributive providence that overtakes them, to the same condition of dishonor to which, by their system and their teaching, they have brought down those eternal principles of God's law. but whosoever shall do and teach them--whose principles and teaching go to exalt the authority and honor of God's law, in its lowest as well as highest requirements. the same shall be called great in the kingdom of heaven--shall, by that providence which watches over the honor of God's moral administration, be raised to the same position of authority and honor to which they exalt the law.

This chapter, and the two that follow it, are a sermon; a famous sermon; the sermon upon the mount. It is the longest and fullest continued discourse of our Saviour that we have upon record in all the gospels. It is a practical discourse; there is not much of the credenda of Christianity in it - the things to be believed, but it is wholly taken up with the agenda - the things to be done; these Christ began with in his preaching; for if any man will do his will, he shall know of the doctrine, whether it be of God. The circumstances of the sermon being accounted for (Mat 5:1, Mat 5:2), the sermon itself follows, the scope of which is, not to fill our heads with notions, but to guide and regulate our practice. I. He proposes blessedness as the end, and gives us the character of those who are entitled to blessedness (very different from the sentiments of a vain world), in eight beatitudes, which may justly be called paradoxes (Mat 5:3-12). II. He prescribes duty as the way, and gives us standing rules of that duty. He directs his disciples, 1. To understand what they are - the salt of the earth, and the lights of the world (Mat 5:13-16). 2. To understand what they have to do - they are to be governed by the moral law. Here is, (1.) A general ratification of the law, and a recommendation of it to us, as our rule (Mat 5:17-20). (2.) A particular rectification of divers mistakes; or, rather, a reformation of divers wilful, gross corruptions, which the scribes and Pharisees had introduced in their exposition of the law; and an authentic explication of divers branches which most needed to be explained and vindicated (Mat 5:20). Particularly, here is an explication, [1.] Of the sixth commandment, which forbids murder (Mat 5:21-26). [2.] Of the seventh commandment, against adulter…

5:19 The realization of the law in Christ means that obedience to all of his commands (see 28:20) is the only acceptable response for his disciples. • Commandment refers to the Old Testament commands (5:18) as now fulfilled in Christ’s teaching (see 5:21-48). • the least in the Kingdom of Heaven: Jesus may mean that such an individual will enter the Kingdom, but only barely and with low status; alternatively, some Jewish evidence suggests that he is referring to damnation (cp. 8:12, where “those for whom the Kingdom was prepared” are eternally excluded).
