The KJB's "depart" in relation to its phrase of some shall depart from the faith matches with the Greek's word " apostisonatai" (from the Greek word "apostasia") meaning in the Greek Textus Receptus editions that the KJB is from & matches the 1611 KJB's words and proves that saved people can/have the ability to apostatize/depart from the faith (they still should not choose to apostatize, but apostasy is a real thing as a real danger to a saved person's physical life in the world/earth in regards to whether a person's life on earth gets any chastened or blessed by God &/or not ):

4 το δε πνευμα ρητως λεγει οτι εν υστεροις καιροις αποστησονται τινες της πιστεως προσεχοντες πνευμασιν πλανοις και διδασκαλιαις δαιμονιων
2 εν υποκρισει ψευδολογων κεκαυτηριασμενων την ιδιαν συνειδησιν
3 κωλυοντων γαμειν απεχεσθαι βρωματων α ο θεος εκτισεν εις μεταληψιν μετα ευχαριστιας τοις πιστοις και επεγνωκοσιν την αληθειαν
4 οτι παν κτισμα θεου καλον και ουδεν αποβλητον μετα ευχαριστιας λαμβανομενον

👉🏻 1598 Beza TR [ Novum Testamentum ]
1 Τὸ δὲ πνεῦμα ῥητῶς λέγει ὅτι ἐν ὑστέροις καιροῖς ἀποστήσονται τινὲς
τῆς πίστεως, προσέχοντες πνεύμασι πλάνοις, καὶ διδασκαλίαις δαιμονίων,
2 Ἐν ὑποκρίσει ψευδολόγων, κεκαυτηριασμένων τὴν ἰδίαν συνείδησιν,
3 Κωλυόντων γαμεῖν, ἀπέχεσθαι βρωμάτων, ἃ ὁ Θεὸς ἔκτισεν εἰς
μετάλημψιν μετὰ εὐχαριστίας τοῖς πιστοῖς καὶ ἐπεγνωκόσι τὴν ἀλήθειαν.
4 Ὅτι πᾶν κτίσμα Θεοῦ, καλόν, καὶ οὐδὲν ἀπόβλητον, μετὰ εὐχαριστίας λαμβανόμενον.

~ 1611 KJB 1 Timothy 4:1-4
Now the Spirit speaketh expresly, that in the latter times some shall depart from the faith, giuing heed to seducing spirits, and doctrines of deuils:
Speaking lies in hypocrisie, hauing their conscience seared with a hote iron,
Forbidding to marry, and commanding to absteine from meates,which God hath created to bee receiued with thankesgiuing of them which beleeue, and know the trueth.
For euery creature of God is good, and nothing to be refused, if it be receiued with thankesgiuing:
