Matthäus 5:18

For verily I say unto you--Here, for the first time, does that august expression occur in our Lord's recorded teaching, with which we have grown so familiar as hardly to reflect on its full import. It is the expression manifestly, of supreme legislative authority; and as the subject in connection with which it is uttered is the Moral Law, no higher claim to an authority strictly divine could be advanced. For when we observe how jealously Jehovah asserts it as His exclusive prerogative to give law to men (Lev 18:1-5; Lev 19:37; Lev 26:1-4, Lev 26:13-16, &c.), such language as this of our Lord will appear totally unsuitable, and indeed abhorrent, from any creature lips. When the Baptist's words--"I say unto you" (Mat 3:9) --are compared with those of his Master here, the difference of the two cases will be at once apparent. Till heaven and earth pass--Though even the Old Testament announces the ultimate "perdition of the heavens and the earth," in contrast with the immutability of Jehovah (Psa 102:24-27), the prevalent representation of the heavens and the earth in Scripture, when employed as a popular figure, is that of their stability (Psa 119:89-91; Ecc 1:4; Jer 33:25-26). It is the enduring stability, then, of the great truths and principles, moral and spiritual, of the Old Testament revelation which our Lord thus expresses. one jot--the smallest of the Hebrew letters. one tittle--one of those little strokes by which alone some of the Hebrew letters are distinguished from others like them. shall in no wise pass from the law, till all be fulfilled--The meaning is that "not so much as the smallest loss of authority or vitality shall ever come over the law." The expression, "till all be fulfilled," is much the same in meaning as "it shall be had in undiminished and endur…

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…
