'Sound' in the Bible

When you hear the sound of marching coming from the tops of the balsam trees, then go out to battle, because God will have gone out ahead of you to destroy the Philistine army."

Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer the priests were appointed to sound the trumpets before the Ark of God, and Obed-edom and Jehiah were trustees for the ark.

"Now as for you, my son Solomon, get to know the God of your father. Serve him with a sound heart and a devoted soul, because the LORD is searching every heart, every plan and thought. He will be found by you, assuming you are seeking him, but if you abandon him, he will abandon you forever.
