Ver. 27,28. The similitude is of the same import with the other, to show that the Pharisees had only a vizard of strictness and holiness, when in the mean time their hearts were full of lusts, hypocrisy, and iniquity. The Jews had two sorts of graves; some for ordinary persons, which appeared not (to which our Saviour likened the Pharisees, Luk_11:44); others that were covered with tombs, which were wont to be kept whited, so as they looked very fair outwardly, but had within nothing but rottenness and putrefaction. To these he compares them in this place. They were men that made a great show, but had nothing of any inward purity or cleanness, but were full of iniquity. Thus Paul called Ananias a whited wall; and, Psa_5:9, the psalmist saith of the throat of the wicked that it is an opensepulchre.
