¹ tn Heb “will call his name Isaac.” The name means “he laughs,” or perhaps “may he laugh” (see the note on the word “laughed” in v. 17).

² tn Or “as an eternal.”

³ tn Heb “he”; the referent (one of the three men introduced in v. 2) has been specified in the translation for clarity. Some English translations have specified the referent as the Lord (cf. RSV, NIV) based on vv. 1, 13, but the Hebrew text merely has “he said” at this point, referring to one of the three visitors. Aside from the introductory statement in v. 1, the incident is narrated from Abraham’s point of view, and the suspense is built up for the reader as Abraham’s elaborate banquet preparations in the preceding verses suggest he suspects these are important guests. But not until the promise of a son later in this verse does it become clear who is speaking. In v. 13 the Hebrew text explicitly mentions the Lord.

⁴ tn The Hebrew construction is emphatic, using the infinitive absolute with the imperfect tense.

⁵ tn Heb “as/when the time lives” or “revives,” possibly referring to the springtime.

⁶ tn Heb “and there will be (הִנֵּה, hinneh) a son for Sarah.”

⁷ tn This is the first of two disjunctive parenthetical clauses preparing the reader for Sarah’s response (see v. 12).

⁸ tn The Hebrew verb פָּלָא (pala’) means “to be wonderful, to be extraordinary, to be surpassing, to be amazing.”

⁹ sn Sarah will have a son. The passage brings God’s promise into clear focus. As long as it was a promise for the future, it really could be believed without much involvement. But now, when it seemed so impossible from the human standpoint, when the Lord fixed an exact date for the birth of the child, the promise became rather overwhelming to Abraham and Sarah. But then this was the Lord of creation, the one they had come to trust. The point of these narratives is that the creation of Abraham’s offspring, which eventually became Israel, is no less a miraculous work of creation than the creation of the world itself.

¹⁰ tn Heb “the words of the Lord are pure words,” i.e., untainted by falsehood or deception (in contrast to the flattery of the evildoers, v. 2).

¹¹ tn Heb “[like] silver purified in a furnace of [i.e., “on”] the ground, refined seven times.” The singular participle מְזֻקָּק (mÿzuqqaq, “refined”) modifies “silver.” The number seven is used rhetorically to express the thorough nature of the action. For other rhetorical/figurative uses of שִׁבְעָתָיִם (shiv’atayim, “seven times”), see Gen 4:15, 24; Ps 79:12; Prov 6:31; Isa 30:26.

¹² sn The words that Jesus predicts here will never pass away. They are more stable and lasting than creation itself. For this kind of image, see Isa 40:8; 55:10-11.

¹³ tn Grk “born according to the flesh”; BDAG 916 s.v. σάρξ 4 has “Of natural descent τὰ τέκνα τῆς σαρκός children by natural descent Ro 9:8 (opp. τὰ τέκνα τῆς ἐπαγγελίας). ὁ μὲν ἐκ τῆς παιδίσκης κατὰ σάρκα γεγέννηται Gal 4:23; cp. vs. 29.”

¹⁴ tc Most mss (א A C D² Ψ 062 Ï lat sy bo) read “we” here, while “you” is found in Ì⁴⁶ B D* F G 0261^vid 0278 33 1739 al sa. It is more likely that a copyist, noticing the first person pronouns in vv. 26 and 31, changed a second person pronoun here to first person for consistency.

¹⁵ tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:11.

¹⁶ tn Grk “before eternal ages.”
