'Within' in the Bible

‘Is not their tent-cord plucked up within them?They die, yet without wisdom.’

“For the arrows of the Almighty are within me,Their poison my spirit drinks;The terrors of God are arrayed against me.

“Is it that my help is not within me,And that deliverance is driven from me?

‘Yet these things You have concealed in Your heart;I know that this is within You:

Whom I myself shall behold,And whom my eyes will see and not another.My heart faints within me!

Yet his food in his stomach is changedTo the venom of cobras within him.

“Because he knew no quiet within him,He does not retain anything he desires.

“Within the walls they produce oil;They tread wine presses but thirst.

“And now my soul is poured out within me;Days of affliction have seized me.

“At night it pierces my bones within me,And my gnawing pains take no rest.

“I am seething within and cannot relax;Days of affliction confront me.

“For I am full of words;The spirit within me constrains me.

“Who can strip off his outer armor?Who can come within his double mail?
