No sooner had Esau departed on his errand than Rebekah set about the accomplishment of her purpose. She told Jacob what had taken place, urging the necessity of immediate action to prevent the bestowal of the blessing, finally and irrevocably, upon Esau. And she assured her son that if he would follow her directions, he might obtain it as God had promised. Jacob did not readily consent to the plan that she proposed. The thought of deceiving his father caused him great distress. He felt that such a sin would bring a curse rather than a blessing. But his scruples were overborne, and he proceeded to carry out his mother's suggestions. It was not his intention to utter a direct falsehood, but once in the presence of his father he seemed to have gone too far to retreat, and he obtained by fraud the coveted blessing.

Næppe var Esau taget af sted, før Rebekka begyndte at gennemføre sine planer. Hun fortalte Jakob, hvad der var sket, og understregede nødvendigheden af øjeblikkelig handling for at forhindre, at velsignelsen endeligt og uigenkaldeligt blev givet til Esau. Hun forsikrede sin søn om, at hvis han ville følge hendes anvisninger, kunne han få velsignelsen, som Gud havde lovet. Jakob gik ikke lige straks ind på den plan, hun fremsatte. Tanken om at bedrage faderen smertede ham meget. Han følte, at en sådan synd snarere ville nedkalde en forbandelse end en velsignelse. Men hans betænkeligheder blev overvundet, og han fulgte moderens forslag. Det var ikke hans hensigt at sige en usandhed, men da han først var i faderens nærhed, så det ud, som om han var gået for langt til at kunne trække sig tilbage, og han opnåede ved svig den eftertragtede velsignelse.
