'Flat' in the Bible

For whatever man he is that has a blemish, he shall not draw near: a blind man, or a lame, or he who has a flat nose, or any deformity,

It shall be that when they make a long blast with the ram's horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall go up every man straight before him."

So the people shouted, and the priests blew the trumpets. It happened, when the people heard the sound of the trumpet, that the people shouted with a great shout, and the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.

When Gideon had come, behold, there was a man telling a dream to his fellow; and he said, "Behold, I dreamed a dream; and behold, a cake of barley bread tumbled into the camp of Midian, and came to the tent, and struck it so that it fell, and turned it upside down, so that the tent lay flat."

Salt is good, but if the salt becomes flat and tasteless, with what do you season it?
