¹ sn Laughed. The Hebrew verb used here provides the basis for the naming of Isaac: “And he laughed” is וַיִּצְחָק (vayyitskhaq); the name “Isaac” is יִצְחָק (yitskhaq), “he laughs.” Abraham’s (and Sarah’s, see 18:12) laughter signals disbelief, but when the boy is born, the laughter signals surprise and joy.

² tn Heb “And he fell on his face and laughed and said in his heart.”

³ tn The imperfect verbal form here carries a potential nuance, as it expresses the disbelief of Abraham.

⁴ tn Heb “to the son of a hundred years.”

⁵ sn It is important to note that even though Abraham staggers at the announcement of the birth of a son, finding it almost too incredible, he nonetheless calls his wife Sarah, the new name given to remind him of the promise of God (v. 15).

⁶ tn Heb “the daughter of ninety years.”

⁷ tn Heb “and Abraham rose up early in the morning and he took.”

⁸ tn Heb “bread,” although the term can be used for food in general.

⁹ tn Heb “He put upon her shoulder, and the boy [or perhaps, “and with the boy”], and he sent her away.” It is unclear how “and the boy” relates syntactically to what precedes. Perhaps the words should be rearranged and the text read, “and he put [them] on her shoulder and he gave to Hagar the boy.”

¹⁰ tn Heb “she went and wandered.”

¹¹ tn Or “desert,” although for English readers this usually connotes a sandy desert like the Sahara rather than the arid wasteland of this region with its sparse vegetation.
