'Confidently' in the Bible

In his days is Judah saved, and Israel dwelleth confidently, And this his name that Jehovah proclaimeth him, 'Our Righteousness.'

Lo, I am gathering them out of all the lands whither I have driven them in Mine anger, and in My fury, and in great wrath, and I have brought them back unto this place, and have caused them to dwell confidently;

In those days is Judah saved, And Jerusalem doth dwell confidently, And this is he whom Jehovah proclaimeth to her: 'Our Righteousness.'

Rise ye, go up unto a nation at rest, Dwelling confidently, an affirmation of Jehovah, It hath no two-leaved doors nor bar, Alone they do dwell.
