In the dark they dig through houses Either the adulterer last mentioned, or rather the thief or robber, whose common practice this is, of whom he spake, Job 24:14; and having, on that occasion, inserted the mention of the adulterer, as one who acted his sin in the same manner as the night thief did, he now returns to the latter again: which they had marked for themselves Distinguishing, by some secret mark, the house of some rich man which they intended to rob, and the part of the house where they resolved to enter it. They know not the light Do not love nor make use of it, but abhor and shun it. For the morning is as the shadow of death Terrible and hateful, because it both discovers them and hinders their practices. If one know them, &c. If they are brought to light, or discovered, they are overwhelmed with deadly horrors and terrors.
