'Within' in the Bible

So was the first attack [in] which Jonathan and {his armor bearer} killed about twenty men within about half of a furrow in an acre of [an] open field.

Should a man arise to pursue you and to seek your life, may the life of my lord be wrapped in the pouch of the living with Yahweh your God. But as for the life of your enemy, he will sling it from within the pocket of the sling!

{And then} in the morning when the wine had gone out of Nabal, his wife told him these words. Then his heart died {within him}, and he became like a stone.
