'Gross' in the Bible

For behold, darkness shall cover the earth, and gross darkness the peoples; but Jehovah will arise upon thee, and his glory shall be seen on thee.

Give glory to Jehovah your God, before he cause darkness, and before your feet stumble upon the mountains of twilight; and ye shall look for light, but he will turn it into the shadow of death, and make it gross darkness.

a day of darkness and gloom, a day of clouds and gross darkness, as the dawn spread upon the mountains; a great people and a strong; there hath not been ever the like, neither shall be any more after them, to the years of generations and generations.

That day is a day of wrath, a day of trouble and distress, a day of ruin and desolation, a day of darkness and gloom, a day of clouds and gross darkness,
