"“Violence shall no more be heard in thy land, Wasting nor destruction within thy borders; But thou shalt call thy walls Salvation, And thy gates Praise. PK 730.1"
"Violence shall no more be heard in thy land, wasting nor destruction within thy borders; but thou shalt call thy walls Salvation, and thy gates Praise."
