'Source' in the Bible

For we have found this man Paul a source of mischief and a disturber of the peace among all the Jews throughout the Empire, and a ringleader in the heresy of the Nazarenes.

yet *we* have but one God, the Father, who is the source of all things and for whose service we exist, and but one Lord, Jesus Christ, through whom we and all things exist.

and so, having been made perfect, He became to all who obey Him the source and giver of eternal salvation.

Every gift which is good, and every perfect boon, is from above, and comes down from the Father, who is the source of all Light. In Him there is no variation nor the slightest suggestion of change.
