Exodus 6:2

וּמֵאָז בָּאתִי אֶל־פַּרְעֹה לְדַבֵּר בִּשְׁמֶךָ הֵרַע לָעָם הַזֶּה וְהַצֵּל לֹא־הִצַּלְתָּ אֶת־עַמֶּֽךָ

For since I came to Pharaoh to speak in Thy name, he hath dealt ill with this people; neither hast Thou delivered Thy people at all.’

וַיֹּאמֶר יְהוָה אֶל־מֹשֶׁה עַתָּה תִרְאֶה אֲשֶׁר אֶֽעֱשֶׂה לְפַרְעֹה כִּי בְיָד חֲזָקָה יְשַׁלְּחֵם וּבְיָד חֲזָקָה יְגָרְשֵׁם מֵאַרְצֽוֹ

And the LORD said unto Moses: ‘Now shalt thou see what I will do to Pharaoh; for by a strong hand shall he let them go, and by a strong hand shall he drive them out of his land.’

וָאֵרָא אֶל־אַבְרָהָם אֶל־יִצְחָק וְאֶֽל־יַעֲקֹב בְּאֵל שַׁדָּי וּשְׁמִי יְהוָה לֹא נוֹדַעְתִּי לָהֶֽם

and I appeared unto Abraham, unto Isaac, and unto Jacob, as God Almighty, but by My name יהוה I made Me not known to them.

וְגַם הֲקִמֹתִי אֶת־בְּרִיתִי אִתָּם לָתֵת לָהֶם אֶת־אֶרֶץ כְּנָעַן אֵת אֶרֶץ מְגֻרֵיהֶם אֲשֶׁר־גָּרוּ בָֽהּ

And I have also established My covenant with them, to give them the land of Canaan, the land of their sojournings, wherein they sojourned.
