'Faints' in the Bible

I remember God; then I am disquieted and I groan;I sigh [in prayer], and my spirit grows faint. Selah.

Therefore my spirit is overwhelmed and weak within me [wrapped in darkness];My heart grows numb within me.

The Lord will consume the glory of Assyria’s forest and of its fruitful garden, both soul and body,And it will be as when a sick man wastes away.
