Joshua 2:12 - Clarke's commentary and critical notes on the Bible

Now therefore, I pray you, swear unto me by the LORD, since I have shewed you kindness, that ye will also shew kindness unto my father's house, and give me a true token: Swear unto me by the Lord - This is a farther proof that this woman had received considerable instruction in the Jewish faith; she acknowledged the true God by his essential character Jehovah; and knew that an oath in his name was the deepest and most solemn obligation under which a Jew could possibly come. Does not this also refer to the command of God, Thou shalt fear the Lord, and shalt swear by his name? See the note on Deuteronomy 6:13.
