LXX	ἐγὼ δὲplugin-autotooltip__default plugin-autotooltip_bigδέ greek δέ is a conjunction that can mean “but” or “and” or “also” or “moreover”. It is a word that is used very frequently in the New Testament, and is often unexpressed and not translated in English. οἶδα ὅτι οὐ προήσεται ὑμᾶς Φαραω βασιλεὺς Αἰγύπτου πορευθῆναι ἐὰν μὴ μετὰ χειρὸς κραταιᾶς
KJV	And I am sure that the king of Egypt will not let you go, no, not by a mighty hand.
