Vayera means “and appeared,” referencing Abba YHWH, appearing to Abraham with two other messengers. The trio brings news that Abraham and Sarah will have a son. Sarah, not believing Abba YHWH, laughs at hearing the pronouncement and then denies she laughed. This is one reason they call their son Yitzchak, “laughter.” Notable here also is that Abraham serves Abba YHWH and His two messengers milk and meat!
After this, we get the dark message of Sodom and Gomorrah’s destruction. Abraham’s nephew Lot and his family must leave immediately to avoid the coming disaster. Also, there is a remarkable “bargaining” session between Abraham and Abba YHWH, as they debate how many righteous souls will spare the entire city. An incident similar to the one where Pharaoh took Sarah happens again with another ruler, with comparable results. The portion ends with the most shocking story of them all, as Abraham is told to kill his son by Abba YHWH Himself!
