Sound speech that cannot be condemned, that he that is of the contrary part may be ashamed, having no evil thing to say of you. Titus 2.8

Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man. Colossians 4.6

My voice shalt thou hear in the morning, O Lord; in the morning will I direct my prayer unto thee, and will look up. Psalms 5.3

The voice of joy, and the voice of gladness; the voice of the bridegroom, and the voice of the bride; the voice of them who shall say, Praise the Lord of hosts; for the Lord is good; for his mercy endures forever; and of those who shall bring the sacrifice of praise into the house of the Lord.  For I will cause to return the captivity of the land, as at the first, saith the Lord. Jeremiah 33.11
