KJV
And he gave him none inheritance in it, no, not [so much as] to set his foot on: yet he promised that he would give it to him for a possession, and to his seed after him, when [as yet] he had no child.
ASV
and he gave him none inheritance in it, no, not so much as to set his foot on: and he promised that he would give it to him in possession, and to his seed after him, when as yet he had no child.
