believe(-r), commit (to trust), put in trust with

Dictionary of Biblical Words:

Although this term only occurs in Acts 5:14¹⁴And believers were the more added to the Lord, multitudes both of men and women.) (Acts 5:14); and 1 Timothy, it is perhaps the best general name for those who are saved; expressing, as it does, the principle of salvation—faith, and not being so generally adopted by the unconverted as “Christians.”
