I have refrained my feet from every evil way
Of error or immorality, forbidden and condemned by the word of
God; every way that is evil in itself, or leads to evil, and in
which evil men walk; and though there may be many snares and
temptations to walk in such a way, yet a good man cannot allow
himself to walk therein, as others do; he has not so learned the
word of God; he is under the influence of divine grace, and
withholds himself from it; he abstains from all appearance of
evil, and lays a restraint, as upon his mouth and lips, so upon
his feet, or guards his walk and conversation. This shows, that
as David had an affection for the word of God, and made great
proficiency in knowledge by it; so it had an influence on his
life and conversation, and his knowledge appeared to be not
merely speculative, but practical: his end, in laying such a
restraint upon his feet, was not out of vain glory, and to gain
popular applause nor through fear of losing his credit among men,
nor of the wrath of God; but out of love to God, and to his word,
as follows:
that I might keep thy word;
such was his love to it, and his regard to the honour of it;
considering whose word it was, and with whose authority it was
clothed, and whose glory was concerned therein; that he was
careful to walk according to it, and in the way that directed to,
and shun every other way.
