Let them curse it that curse the day, who are ready to raise up their mourning.
Them ... that curse the day. If mourning be the right rendering in the latter clause of this verse; these words refer to the hired mourners of the dead (Jeremiah 9:17). But the Hebrew for mourning х liwyaataan (H3882)] elsewhere always denotes an animal, whether it be the crocodile or some huge serpent (Isaiah 27:1) that is meant by leviathan х Liwyaataan (H3882)]. Therefore the expression cursers of day refers to magicians who were believed to be able by charms to make a day one of evil omen. So Balaam (Numbers 22:5). This accords with Umbreit's view (Job 3:5); or to the Ethiopians and Atlantes, who 'used to curse the sun at his rising, for burning up them and their country' (Herodotus). Necromancers claimed power to control or rouse wild beasts at will; as the Indian serpent-chambers at this day (Psalms 58:5). Job does not say they had the power they claimed; but, supposing they had, may they curse the day. Schuttens renders it by supplying words, as follows: Let those that are ready for anything, call it (the day) the raiser up of leviathan - i:e., of a host of evils.
