'Insides' in the Bible

My insides feel like unvented wine, like it's about to burst like a new wineskin.

My insides are burning and my body is unhealthy.

Therefore my insides moan like a lyre for Moab, and my innermost being for Kir-hareseth.

Look, LORD, how distressed I am; all my insides are churning. My heart is troubled within me, because I vigorously rebelled. Outside the sword brings loss of life, while at home death rules.

My eyes are worn out from crying, my insides are churning, My emotions pour out in grief because my people are destroyed Children and infants faint in the streets of the city.
