'Thickest' in the Bible

And he wrote in the letter saying, Set Urijah in the front of the thickest fight, and withdraw from him, that he may be smitten and die.

‘Through your messengers you have reproached the Lord,And you have said, “With my many chariotsI came up to the heights of the mountains,To the remotest parts of Lebanon;And I cut down its tall cedars and its choice cypresses.And I entered its farthest lodging place, its thickest forest.

“Through your servants you have reproached the Lord,And you have said, ‘With my many chariots I came up to the heights of the mountains,To the remotest parts of Lebanon;And I cut down its tall cedars and its choice cypresses.And I will go to its highest peak, its thickest forest.
