What Does Matthew 1:7 Mean?

**3-6. And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram; 4. And Aram begat Aminadab; and Aminadab begat Naasson; and Naasson begat Salmon; 5. And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; 6. And Jesse begat David the king; and David the king begat Solomon of her of Urias--**Four women are here introduced; two of them Gentiles by birth--Rachab and Ruth; and three of them with a blot at their names in the Old Testament--Thamar, Rachab, and Bath-sheba. This feature in the present genealogy--herein differing from that given by Luke--comes well from him who styles himself in his list of the Twelve, what none of the other lists do, "Matthew the publican"; as if thereby to hold forth, at the very outset, the unsearchable riches of that grace which could not only fetch in "them that are afar off," but teach down even to "publicans and harlots," and raise them to "sit with the princes of his people." David is here twice emphatically styled "David the king," as not only the first of that royal line from which Messiah was to descend, but the one king of all that line from which the throne that Messiah was to occupy took its name--"the throne of David." The angel Gabriel, in announcing Him to His virgin-mother, calls it "the throne of David His father," sinking all the intermediate kings of that line, as having no importance save as links to connect the first and the last king of Israel as father and son. It will be observed that Rachab is here represented as the great-grandmother of David (see Ru 4:20-22; 1Ch 2:11-15)--a thing not beyond possibility indeed, but extremely improbable, there being about four centuries between them. There can hardly be a doubt that one or two intermediate links are omitted.
