Beraishit 12.3- בראשית

Be Like Abraham!

3.’And I will bless those that will bless you, and he who curses you I will curse- וַאֲבָרְכָה מְבָרְכֶיךָ וּמְקַלֶּלְךָ אָאֹר (954=18); and through you shall all the families of the earth be blessed- וְנִבְרְכוּ בְךָ כֹּל מִשְׁפְּחֹת הָאֲדָמָה(1719=18 counting final Kaf as 500).

Rashi comments here that there is no greater blessing a man can give to his son than by saying “Be like Abraham”-תהא כאברהם.

Be like Abraham

תהא כאברהם

674=17=8 or 1234=10=1 (Mem 600)

674+1234=1908=18

From this gematria we can understand why there can be no greater blessing than this as at one and the same time to a blessing in the physical world (1)  and a blessing in the spiritual world (8).

The gematriot combined make 18 which is the gematria of the word "Hai" “life”-חי.

This is the of Name of Hashem before and after its division when the universe was created.

The gematria of the words “all the families of the earth”- כֹּל מִשְׁפְּחֹת הָאֲדָמָה is 933+3 words=18.

The only time that all the families of the earth will be blessed is when the descendants of Abraham the Jewish People will be given free rule over the Temple Mount in Jerusalem to rebuild the Third Temple.

Then the nations of the world will be blessed through them.

This will only happen when the Jewish People return to Hashem through repentance.

This will happen with the arrival of Mashiach.

May he come speedily in our days!
