يعقوب ١:٨

double-minded--literally, "double-souled," the one soul directed towards God, the other to something else. The Greek favors ALFORD'S translation, "He (the waverer, Jam 1:6) is a man double-minded, unstable," &c.; or better, BEZA'S. The words in this Jam 1:8 are in apposition with "that man," Jam 1:7; thus the "us," which is not in the original, will not need to be supplied, "A man double-minded, unstable in all his ways!" The word for "double-minded" is found here and in Jam 4:8, for the first time in Greek literature. It is not a hypocrite that is meant, but a fickle, "wavering" man, as the context shows. It is opposed to the single eye (Mat 6:22).

After the inscription and salutation (Jam 1:1) Christians are taught how to conduct themselves when under the cross. Several graces and duties are recommended; and those who endure their trials and afflictions as the apostle here directs are pronounced blessed and are assured of a glorious reward (Jam 1:2-12). But those sins which bring sufferings, or the weakness and faults men are chargeable with under them, are by no means to be imputed to God, who cannot be the author of sin, but is the author of all good (Jam 1:13-18). All passion, and rash anger, and vile affections, ought to be suppressed. The word of God should be made our chief study: and what we hear and know of it we must take care to practise, otherwise our religion will prove but a vain thing. To this is added an account wherein pure religion consists (Jam 1:19-27).

1:8 Their loyalty is divided between God and the world (literally They are double-minded): James might have created the Greek word used here. He emphasizes the need for confidence in God alone.
