Psalms 119:118

Thou hast trodden down all them that err from thy statutes,
&c.] That wander from the way of the Lord's commandments; that deviate from his precepts, go astray constantly and wilfully; a people that err in their hearts, and with all their hearts. These the Lord treads down, as mire in the streets, as grapes in a winepress; which shows his abhorrence of them, his indignation at them, and how easily they are subdued under him;

for their deceit [is] falsehood:
or, "their hypocrisy [is] a lie" ^F13: the appearance they make is a false one; they appear outwardly righteous, but are inwardly wicked; have a form of godliness, but deny the power of it: or all their deceitful doctrines are lies in hypocrisy, though dressed up with all the art and cunning they are masters of; or all their subtle schemes to corrupt and subvert the true doctrines of the word are in vain and to no purpose.
