'Devoting' in the Bible

But the king will rejoice in God;Everyone who swears by Him [honoring the true God, acknowledging His authority and majesty] will glory,For the mouths of those who speak lies will be stopped.

They were continually and faithfully devoting themselves to the instruction of the apostles, and to fellowship, to eating meals together and to prayers.

For this same reason you pay taxes, for civil authorities are God’s servants, devoting themselves to governance.
