I am dealing with the Parasha Vayezah at this time… right at the beginning it is reported that Ya’akov went towards Haran, after leaving Beershaba. On his way he came to a place – it had become dark and he had to spend the night – where he dreamed the famous dream of the ladder to heaven, on which messengers ascend and descend.
In this dream it was important that the Eternal was above it. Hashem had his observation of what was happening the whole time. He says that the G-d of Avraham is his father and that he is the G-d of Yitchak. The land on which he, Ya’akov, lies, Hashem gives to him and his seed – that is, his children. Hashem goes on to say that he will spread out like the dust of the earth in the evening and in the morning… and that with him, Ya’akov, all the families of the earth will bless themselves.
This is very important because it contains a double message: Firstly, that Ya’akov and his children have a special role and responsibility for life on this planet; and secondly, that the nations bless each other with Ya’akov – not against him.

The dream continues, in which Hashem promises that he is with him and protects him wherever Ya’akov goes.

I have always thought about Ya’akov raising the stones of his headrest into a pillar and pouring oil on them; it is a clear reference to the Bet haMikdash in Jerusalem, and that it is precisely this that is being built. Ya’akov therefore gave the name Bet-El – House of G-d to this place where he dreamed and woke up again.

Shavua Tov!
