'Quietness' in the Bible

Behold, a son shall be born to thee, who shall be a man of rest; and I will give him rest from all his enemies round about; for his name shall be Solomon, and I will give peace and quietness unto Israel in his days:

Because he knew no quietness within him, He shall not save aught of that wherein he delighteth.

When he giveth quietness, who then can condemn? And when he hideth his face, who then can behold him? Alike whether it be done unto a nation, or unto a man:

Better is a dry morsel, and quietness therewith, Than a house full of feasting with strife.

Better is a handful, with quietness, than two handfuls with labor and striving after wind.

For thus said the Lord Jehovah, the Holy One of Israel, In returning and rest shall ye be saved; in quietness and in confidence shall be your strength. And ye would not:

And the work of righteousness shall be peace; and the effect of righteousness, quietness and confidence for ever.
