But first must he suffer many things
By cruel mockings, spitting, buffeting, scourging, and, at last,
death itself; all which must be, and were before his day came, or
he entered into his glory, or came in it:
and be rejected of this generation;
as the Messiah, and be treated with the utmost scorn and
contempt, and in the most base and ignominious manner: being put
to the death of the cross, and hanged upon the accursed tree: all
which were necessary, "must" be; on account of the purposes and
decrees of God; the covenant engagements of Christ; the
predictions of the prophets of the Old Testament, and his own;
and the salvation of his people.
