'Render' in the Bible

Are they not all ministering spirits, sent out to render service for the sake of those who will inherit salvation?

Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil,

And no creature is hidden from God, but everything is naked and exposed to the eyes of him to whom we must render an account.

Obey your [spiritual] leaders and submit to them [recognizing their authority over you], for they are keeping watch over your souls and continually guarding your spiritual welfare as those who will give an account [of their stewardship of you]. Let them do this with joy and not with grief and groans, for this would be of no benefit to you.
