'Regarding' in the Bible

So I instructed you at that time regarding everything you should do.

And thus [also] you shall do regarding his donkey, and thus you shall do concerning his garment, and so you shall do with respect to all [of] the lost property of your countryman that is lost from him and you find it; you are not allowed to withhold help.

And this regarding Judah; so he said,“Hear, O Lord, the voice of Judah,And bring him to his people.With his hands he contended for them,And may You be a help against his adversaries.”
