'Fallen' in the Bible

"If a man's hair has fallen from his head, he is bald. He is clean.

If his hair has fallen off from the front part of his head, he is forehead bald. He is clean.

You shall not glean your vineyard, neither shall you gather the fallen grapes of your vineyard; you shall leave them for the poor and for the foreigner. I am Yahweh your God.
