New Defender's Study Bible Notes
8:9 mayest dig brass. Brass is mostly copper, and the Hebrew word is the same as for “copper.” At one time critics said that Canaan had no copper deposits, but it was later found that ancient copper and iron mines were extensively developed in southern Palestine during the time of Solomon.
8:18 he that giveth thee. It is salutary for believers always to remember that God owns all things and He has made all things–including our own lives and abilities. Pride is the sin of the devil; nothing we have and nothing we can do can warrant boasting; it all comes from God.
