G2620–κατακαυχάομαι–katakauchaomai

do not boast against the branches; and if thou dost boast, thou dost not bear the root, but the root thee!

κατακαυχῶ katakauchō “do boast”κατακαυχᾶσαι, katakauchasai “you boast against [them],”

for the judgment without kindness `is' to him not having done kindness, and exult doth kindness over judgment.

κατακαυχᾶται katakauchatai “it triumphs over”

and if bitter zeal ye have, and rivalry in your heart, glory not, nor lie against the truth;

κατακαυχᾶσθε katakauchasthe “do boast [of it]”
