If David then call him Lord
That is, the Messiah, which is taken for granted, nor could the
Pharisees deny it,
how is he his son?
The question is to be answered upon true and just notions of the
Messiah, but unanswerable upon the principles of the Pharisees;
who expected the Messiah only as a mere man, that should be of
the seed of David, and so his son; and should sit upon his
throne, and be a prosperous and victorious prince, and deliver
them out of the hands of their temporal enemies: they were able
to make answer to the question, separately considered, as that he
should be of the lineage and house of David; should lineally
descend from him, be of his family, one of his offspring and
posterity, and so be properly and naturally his son; but how he
could be so, consistent with his being David's Lord, puzzled
them. Had they understood and owned the proper divinity of the
Messiah, they might have answered, that as he was God, he was
David's Lord, his maker, and his king; and, as man, was David's
son, and so both his root and offspring; and this our Lord meant
to bring them to a confession of, or put them to confusion and
silence, which was the consequence.
