'Companions' in the Bible

Now {Paul and his companions} put out to sea from Paphos [and] came to Perga in Pamphylia, but John departed from them [and] returned to Jerusalem.

And the city was filled with the tumult, and with one purpose they rushed into the theater, seizing Gaius and Aristarchus, Macedonians [who were] traveling companions of Paul.

You have loved righteousness and hated lawlessness; because of this God, your God, has anointed you with the olive oil of joy more than your companions.
