'Themselves' in the Bible

The descendants of Levi therefore purified themselves, washed their clothes, and then Aaron presented them as wave offerings to the LORD. Aaron provided atonement for them to purify them.

So they got up early the next morning and traveled to the top of the mountain, telling themselves, "Look, we're here and we're going to go up to the place that the LORD had spoken about, even though we've sinned."
