Fat; thick.

For this people's heart is waxed GROSS, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them. ( Matthew 13:15 )
