'Sounding' in the Bible
And the Lord came down in the cloud and spoke to him, and took of the Spirit that was upon him and put It upon the seventy elders; and when the Spirit rested upon them, they prophesied [sounding forth the praises of God and declaring His will]. Then they did so no more.
And a young man ran to Moses and said, Eldad and Medad are prophesying [sounding forth the praises of God and declaring His will] in the camp.
Thus all Israel brought up the ark of the covenant of the Lord with shouting, sound of the cornet, trumpets, and cymbals, sounding aloud with harps and lyres.
Yet to us God has unveiled and revealed them by and through His Spirit, for the [Holy] Spirit searches diligently, exploring and examining everything, even sounding the profound and bottomless things of God [the divine counsels and things hidden and beyond man's scrutiny].
