וְאֶת־תַּזְנוּתֶ֤יהָ מִמִּצְרַ֙יִם֙ לֹ֣א עָזָ֔בָה כִּ֤י אוֹתָהּ֙ שָׁכְב֣וּ בִנְעוּרֶ֔יהָ וְהֵ֥מָּה עִשּׂ֖וּ דַּדֵּ֣י בְתוּלֶ֑יהָ וַיִּשְׁפְּכ֥וּ תַזְנוּתָ֖ם עָלֶֽיהָ׃
Neither hath she left her harlotries brought from Egypt; for in her youth they lay with her, and they bruised her virgin breasts; and they poured out their lust upon her.
Rashi on Ezekiel
And her harlotries from Egypt she did not abandon They relied also upon the kings of Egypt, for we find (II Kings 17:4), concerning Hoshea the son of Elah, that he sent messengers to So the king of Egypt.
Rashi on Ezekiel
for they had lain with her, etc. And since then, “they poured out their harlotry upon her” - her promiscuous spirit entered her from the days of her youth.
