What Does Genesis 27:9 Mean?

Isaac said: "May God give you heaven's dew and earth's richness, an abundance of grain and new wine. May nations serve you and peoples bow down to you. Be lord over your brothers, and may the sons of your mother bow down to you. May those who curse you be cursed and those who bless you be blessed." The blessing Isaac gives Jacob (believing him to be Esau) is a complete covenant blessing: material abundance (heaven's dew, earth's richness, grain and wine), political supremacy (nations serving, peoples bowing), familial authority (lord over brothers), and the Abrahamic reversal of curse and blessing. The blessing is comprehensive, irrevocable, and, as Isaac will discover, given to the wrong son by his own reckoning.

The content of the blessing takes up the Abrahamic covenant's political dimension: "may those who curse you be cursed and those who bless you be blessed" directly echoes Genesis 12:3. The dying patriarch passes the covenant's protective clause to the son he believes he is blessing. The irony is precise: the protective clause of the Abrahamic covenant is given in the course of an act of deception. The blessing is real; the process that secured it was not.

The blessing that makes the recipient "lord over brothers" is the oracle of reversal made explicit: the younger son receives the authority over the older. What the oracle declared, "the older will serve the younger", is now spoken by the patriarch as a formal blessing, even though the patriarch believes he is blessing the older. The reversal happens through the patriarch's act precisely because the patriarch does not know he is enacting it. The divine purpose moves through human ignorance and human deception to produce the outcome the oracle declared before either son was born.
