The Targum is,"as an abortive and a mole, which are blind and see not the sun.''So Jarchi renders it a "mole", agreeably to the Talmud . Or, "let them not see the sun" ; let them die, and never see the sun in the firmament any more; Christ, the sun of righteousness; nor enjoy the favour of God, and the light of his countenance; nor have the light of life, or eternal glory and happiness; see Ps 49:19.
