2:7 So went Satan forth from the presence of the LORD, and smote Job with sore {h} boils from the sole of his foot unto his crown.
(h) This sore was most vehement, with which God also plagued the Egyptians, Ex 9:9 and threatened to punish rebellious people, De 28:27 so that this temptation was most grievous: for if Job had measured God's favour by the vehemency of his disease, he might have thought that God had cast him off.
2:7 Boils - Like those inflicted upon the Egyptians, which are expressed by the same word, and threatened to apostate Israelites, Deut 28:27, whereby he was made loathsome to himself, and to his nearest relations, and filled with consuming pains in his body, and no less torments and anguish in his mind.
2:7-10 The devil tempts his own children, and draws them to sin, and afterwards torments, when he has brought them to ruin; but this child of God he tormented with affliction, and then tempted to make a bad use of his affliction. He provoked Job to curse God. The disease was very grievous. If at any time we are tried with sore and grievous distempers, let us not think ourselves dealt with otherwise than as God sometimes deals with the best of his saints and servants. Job humbled himself under the mighty hand of God, and brought his mind to his condition. His wife was spared to him, to be a troubler and tempter to him. Satan still endeavours to draw men from God, as he did our first parents, by suggesting hard thoughts of Him, than which nothing is more false. But Job resisted and overcame the temptation. Shall we, guilty, polluted, worthless creatures, receive so many unmerited blessings from a just and holy God, and shall we refuse to accept the punishment of our sins, when we suffer so much less than we deserve? Let murmuring, as well as boasting, be for ever done away. Thus far Job stood the trial, and appeared brightest in the furnace of affliction. There might be risings of corruption in his heart, but grace had the upper hand.
