Genesis/Bereishit 12Both Lech Lecha and Vayelech have the same linguistic root, (ה ל כ (ך heh, lamed, chof, to go.
לך לך Lech Lecha
1 וַיֹּ֤אמֶר יְהוָה֙ אֶל־אַבְרָ֔ם לֶךְ־לְךָ֛ מֵאַרְצְךָ֥ וּמִמּֽוֹלַדְתְּךָ֖ וּמִבֵּ֣ית אָבִ֑יךָ אֶל־הָאָ֖רֶץ אֲשֶׁ֥ר אַרְאֶֽךָּ׃
The LORD said to Abram, “Go forth from your native land and from your father’s house to the land that I will show you.
2 וְאֶֽעֶשְׂךָ֙ לְג֣וֹי גָּד֔וֹל וַאֲבָ֣רֶכְךָ֔ וַאֲגַדְּלָ֖ה שְׁמֶ֑ךָ וֶהְיֵ֖ה בְּרָכָֽה׃
I will make of you a great nation, And I will bless you; I will make your name great, And you shall be a blessing.
וילך Vayelech1 וַיֵּ֖לֶךְ מֹשֶׁ֑ה וַיְדַבֵּ֛ר אֶת־הַדְּבָרִ֥ים הָאֵ֖לֶּה אֶל־כָּל־יִשְׂרָאֵֽל׃
Moses went and spoke these things to all Israel.
וַֽיהוָ֞ה ה֣וּא ׀ הַהֹלֵ֣ךְ לְפָנֶ֗יךָ ה֚וּא יִהְיֶ֣ה עִמָּ֔ךְ לֹ֥א יַרְפְּךָ֖ וְלֹ֣א יַֽעַזְבֶ֑ךָּ לֹ֥א תִירָ֖א וְלֹ֥א תֵחָֽת׃ 8
And the LORD Himself will go before you. He will be with you; He will not fail you or forsake you. Fear not and be not dismayed!”
In Bereishit, which is in the beginning of the Bible/Torah, Gd tells Abram (Abraham) to go to a land of Gd's choosing, and Gd will make him a great nation. Then in one of the very last lines in the Torah, Moshe went (past tense of "go") to the Jewish People, those descended from Abram and reminds them that Gd will always be with them, and they shouldn't lose confidence.
While the politicians here in Israel are fighting over positions and honors, we must never forget that our TRUE LEADER is GD ALMIGHTY. It's Gd who protects us, not the IDF or Iron Dome. Last week we celebrated, Rosh Hashanah, the beginning of the Jewish Year, and this week we'll be praying and fasting on Yom Kippur, beseeching Gd to forgive our sins.
May all the Jewish People return to genuine Jewish Life, of Mitzvot and kindness to one another here in the Land Gd gave us.
