NET

22 Notice therefore the kindness and harshness of God—harshness toward those who have fallen, but God’s kindness toward you, provided you continue in his kindness; otherwise you also will be cut off.

Darby

22 Behold then [the] goodness and severity of God: upon them who have fallen, severity; upon thee goodness of God, if thou shalt abide^D8140 in goodness, since [otherwise] *thou* also wilt be cut away.

Darby Bible Notes

abide - The subjunctive, 'if thou shouldest abide,' or 'abidest.' There are three degrees of condition in Greek. indicative, if the fact arrives; subjunctive, doubtful if it will; and conditional, of uncertain probability.

KJV

22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in [his] goodness: otherwise thou also shalt be cut off.
