 oath (Deu 29:11, Deu 29:13). תּעשׂה אם “that thou do not:” אם a particle of negation used in an oath (Gen 14:23, etc.). (On the verb with zere, see Ges. §75, Anm. 17; Ewald, §224.) - The same day Isaac's servants informed him of the well which they had dug; and Isaac gave it the name Shebah (שׁבעה, oath), in commemoration of the treaty made on oath. “ Therefore the city was called Beersheba.” This derivation of the name does not shut the other (Gen 21:31) out, but seems to confirm it.

verses 1-4
When Isaac had grown old, and his eyes were dim, so that he could no longer see (מראת from seeing, with the neg. מן as in Gen 16:2, etc.), he wished, in the consciousness of approaching death, to give his blessing to his elder son. Isaac was then in his 137th year, at which age his half-brother Ishmael had died fourteen years before; and this, with the increasing infirmities of age, may have suggested the thought
