And Joseph called the name of the firstborn Manasseh
Which signifies forgetfulness, as the reason of it shows: for God, [said he], hath made me forget all my toil, and all my
father's house;
all his toil and labour in Potiphar's house, and especially in the prison; and all the injuries his brethren had done him; all this he was made to forget by the grandeur and honour, wealth and riches, power and authority he was possessed of; and indeed he had so much business upon his hands, that he had scarce time to think of his father, and his family.
