22:20-30 The Jewish state is described under a threefold character. Very haughty in a day of peace and safety. Very fearful on alarm of trouble. Very much cast down under pressure of trouble. Many never are ashamed of their sins till brought by them to the last extremity. The king shall close his days in bondage. Those that think themselves as signets on God's right hand, must not be secure, but fear lest they should be plucked thence. The Jewish king and his family shall be carried to Babylon. We know where we were born, but where we shall die we know not; it is enough that our God knows. Let it be our care that we die in Christ, then it will be well with us wherever we die, thought it may be in a far country. The Jewish king shall be despised. Time was when he was delighted in; but all those in whom God has no pleasure, some time or other, will be so lowered, that men will have no pleasure in them. Whoever are childless, it is the Lord that writes them so; and those who take no care to do good in their days, cannot expect to prosper. How little is earthly grandeur to be depended upon, or flourishing families to be rejoiced in! But those who hear the voice of Christ, and follow him, have eternal life, and shall never perish, neither shall any enemy pluck them out of his almighty hands.

29, 30. O earth! earth! earth!—Jeconiah was not actually without offspring (compare Jer 22:28, "his seed"; 1Ch 3:17, 18; Mt 1:12), but he was to be "written childless," as a warning to posterity, that is, without a lineal heir to his throne. It is with a reference to the three kings, Shallum, Jehoiakim, and Jeconiah, that the earth is thrice invoked [Bengel]. Or, the triple invocation is to give intensity to the call for attention to the announcement of the end of the royal line, so far as Jehoiachin's seed is concerned. Though Messiah (Mt 1:1-17), the heir of David's throne, was lineally descended from Jeconiah, it was only through Joseph, who, though His legal, was not His real father. Matthew gives the legal pedigree through Solomon down to Joseph; Luke the real pedigree, from Mary, the real parent, through Nathan, brother of Solomon, upwards (Lu 3:31).

no man of his seed … upon the throne—This explains the sense in which "childless" is used. Though the succession to the throne failed in his line, still the promise to David (Ps 89:30-37) was revived in Zerubbabel and consummated in Christ.
