Yesaya 7:2

7:2 It was reported to the family ¹  of David, “Syria has allied with ²  Ephraim.” They and their people were emotionally shaken, just as the trees of the forest shake before the wind. ³ 

Yesaya 7:13

7:13 So Isaiah replied, ⁴  “Pay attention, ⁵  family ⁶  of David. ⁷  Do you consider it too insignificant to try the patience of men? Is that why you are also trying the patience of my God?

Lukas 1:69

1:69 For ⁸  he has raised up ⁹  a horn of salvation ¹⁰  for us in the house of his servant David, ¹¹ 

[7:2]  ¹ tn Heb “house.” In this context the “house of David” includes King Ahaz, his family, and the royal court. See also Jer 21:12; Zech 12:7-8, 10, 12, for a similar use of the phrase.

[7:2]  ² tn Heb “rests upon.” Most understand the verb as נוּחַ (nuakh, “rest”), but HALOT 685 s.v. II נחה proposes that this is a hapax legomenon which means “stand by.”

[7:2]  ³ tn Heb “and his heart shook and the heart of his people shook, like the shaking of the trees of the forest before the wind.” The singular pronoun “his” is collective, referring to the Davidic house/family. לֵבָב (levav, “heart”) here refers to the seat of the emotions.

[7:13]  ⁴ tn Heb “and he said.” The subject is unexpressed, but the reference to “my God” at the end of the verse indicates the prophet is speaking.

[7:13]  ⁵ tn The verb is second plural in form, because the prophet addresses the whole family of David. He continues to use the plural in v. 14 (with one exception, see the notes on that verse), but then switches back to the second singular (addressing Ahaz specifically) in vv. 16-17.

[7:13]  ⁶ tn Heb “house.” See the note at v. 2.

[7:13]  ⁷ sn The address to the “house of David” is designed to remind Ahaz and his royal court of the protection promised to them through the Davidic covenant. The king’s refusal to claim God’s promise magnifies his lack of faith.

[1:69]  ⁸ tn Grk “and,” but specifying the reason for the praise in the psalm.

[1:69]  ⁹ sn The phrase raised up means for God to bring someone significant onto the scene of history.

[1:69]  ¹⁰ sn The horn of salvation is a figure that refers to the power of Messiah and his ability to protect, as the horn refers to what an animal uses to attack and defend (Ps 75:4-5, 10; 148:14; 2 Sam 22:3). Thus the meaning of the figure is “a powerful savior.”

[1:69]  ¹¹ sn In the house of his servant David is a reference to Messiah’s Davidic descent. Zechariah is more interested in Jesus than his own son John at this point.
