For without cause have they hid for me their net in a pit,.... This is said in allusion to the custom of digging pits, and putting nets into them, for the catching of wild beasts; and covering them with straw or dust, or such like things, as Jarchi observes, that they might not be discerned; and which intends the secret and crafty methods taken by David's enemies to ensnare him and destroy him; though he had given them no cause to use him in such a manner; which is an aggravation of their sins, and a reason of the above imprecations, as well as of what follows: and in the same manner, and without any just cause, Christ and his members have been treated by wicked men, and therefore their damnation is just, and will be inevitable: which without cause they have digged for my soul; which is added for further explanation's sake, and to aggravate their sin, and to show the justness of their punishment.
