'From the Lord' in the Bible

But an angel from the Lord one night [miraculously] opened the jail doors and released them, saying,

[Meanwhile] an angel [sent] from the Lord spoke to Philip and said, "Get up and travel south on the road from Jerusalem to Gaza; that is a deserted region."

[Then it happened]: [Suddenly] an angel from the Lord stood beside Peter as a light shone into his cell. [The angel] gently struck his side, waking him up, saying, "Get up quickly." His chains fell from his hands.

But I do not consider my life to be of value, as precious to me, [when compared to the importance of] accomplishing my task and the mission I received from the Lord Jesus to declare the good news of God's unearned favor [through Christ].
