John Gill's Bible Commentary Ver. 6. Wherefore they are no more twain , etc.] They were two before marriage, but now no more so; not but that they remain two distinct persons, but one flesh ; or, as the Syriac, Arabic, Persic, and Ethiopic versions read, one body: hence the wife is to beloved by the husband as his own body, as himself, as his own flesh, ( Ephesians 5:28,29). what therefore God hath joined together ; or, by the first institution of marriage, has declared to be so closely united together, as to be, as it were, one flesh, and one body, as husband and wife are; let no man put asunder ; break the bond of union, dissolve the relation, and separate them from each other, for every trivial thing, upon any slight occasion, or for anything; but what is hereafter mentioned. The sense is, that the bond of marriage being made by God himself, is so sacred and inviolable, as that it ought not to be dissolved by any man; not by the husband himself, or any other for him; nor by any state or government, by any prince or potentate, by any legislator whatever; no, not by Moses himself, who is, at least, included, if not chiefly designed here, though not named, to avoid offence: and God and man being opposed in this passage, shows, that marriage is an institution and appointment of God, and therefore not to be changed and altered by man at his pleasure; this not merely a civil, but a sacred affair, in which God is concerned.
Matthew Henry Commentary
Verses 3-12 - The Pharisees were desirous of drawing something from Jesus which the might represent as contrary to the law of Moses. Cases about marriag have been numerous, and sometimes perplexed; made so, not by the law of God, but by the lusts and follies of men; and often people fix what they will do, before they ask for advice. Jesus replied by askin whether they had not read the account of the creation, and the firs example of marriage; thus pointing out that every departure therefro was wrong. That condition is best for us, and to be chosen and kept to accordingly, which is best for our souls, and tends most to prepare u for, and preserve us to, the kingdom of heaven. When the gospel i really embraced, it makes men kind relatives and faithful friends; i teaches them to bear the burdens, and to bear with the infirmities of those with whom they are connected, to consider their peace an happiness more than their own. As to ungodly persons, it is proper tha they should be restrained by laws, from breaking the peace of society And we learn that the married state should be entered upon with grea seriousness and earnest prayer.

Vincent's NT Word Studies
6. What (o). Not those. Christ is contemplating, not the individuals, but the unity which God cemented; and so Wyc., that thing that God enjoined; i.e., knit together. The aorist tense (denoting the occurrence of an event at some past time, considered as a momentary act) seems to refer to the original ordinance of God at the creation (ver. 4).
Robertson's NT Word Studies
19:6 {What therefore God hath joined together} (ho oun ho qeos sunezeuxen). Note "what," not "whom." The marriage relation God has made. "The creation of sex, and the high doctrine as to the cohesion it produces between man and woman, laid down in Gen., interdict separation" (Bruce). The word for "joined together" means "yoked together," a common verb for marriage in ancient Greek. It is the timeless aorist indicative (sunezeuxen), true always. {Bill} (biblion). A little biblos (see on 1:1), a scroll or document (papyrus or parchment). this was some protection to the divorced wife and a restriction on laxity.
