'Retained' in the Bible

Then look, there was {one in the form of a human}; he touched my lips and I opened my mouth and I spoke and I said to the [one] standing {before me}, "My lord, because of the vision my anxieties fell upon me and I [have] not retained [my] strength.

If you forgive the sins of any, they are forgiven them. If you retain [the sins] of any, they are retained."
