'Devoting' in the Bible

These all with one mind were continually devoting themselves to prayer, along with the women, and Mary the mother of Jesus, and with His brothers.

They were continually devoting themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.

But when Silas and Timothy came down from Macedonia, Paul began devoting himself completely to the word, solemnly testifying to the Jews that Jesus was the Christ.
