'Mode' in the Bible

Now the whole earth spoke one language and used the same words (vocabulary).

Manoah said, “Now when your words come to pass, what shall be the boy’s mode of life and his vocation?”

Now this was the custom in former time in Israel concerning redemption and concerning exchange, to confirm the whole matter: a man drew off his sandal, and gave it to his neighbour, and this was the mode of attestation in Israel.
