'Stedfastly' in the Bible

and they were continuing stedfastly in the teaching of the apostles, and the fellowship, and the breaking of the bread, and the prayers.

And Peter, having looked stedfastly toward him with John, said, 'Look toward us;'

and being full of the Holy Spirit, having looked stedfastly to the heaven, he saw the glory of God, and Jesus standing on the right hand of God,

at which having looked stedfastly, I was considering, and I saw the four-footed beasts of the earth, and the wild beasts, and the creeping things, and the fowls of heaven;

And Saul -- who also is Paul -- having been filled with the Holy Spirit, and having looked stedfastly on him,

this one was hearing Paul speaking, who, having stedfastly beheld him, and having seen that he hath faith to be saved,

and if the ministration of the death, in letters, engraved in stones, came in glory, so that the sons of Israel were not able to look stedfastly to the face of Moses, because of the glory of his face -- which was being made useless,

and are not as Moses, who was putting a vail upon his own face, for the sons of Israel not stedfastly to look to the end of that which is being made useless,
