Yesaya 28:16

28:16 Therefore, this is what the sovereign master, the Lord, says:

“Look, I am laying ¹  a stone in Zion,

an approved ²  stone,

set in place as a precious cornerstone for the foundation. ³ 

The one who maintains his faith will not panic. ⁴ 

Efesus 2:20

2:20 because you have been built ⁵  on the foundation of the apostles and prophets, ⁶  with Christ Jesus himself as ⁷  the cornerstone. ⁸ 

[28:16]  ¹ tc The Hebrew text has a third person verb form, which does not agree with the first person suffix that precedes. The form should be emended to יֹסֵד (yosed), a Qal active participle used in a present progressive or imminent future sense.

[28:16]  ² tn Traditionally “tested,” but the implication is that it has passed the test and stands approved.

[28:16]  ³ sn The reality behind the metaphor is not entirely clear from the context. The stone appears to represent someone or something that gives Zion stability. Perhaps the ideal Davidic ruler is in view (see 32:1). Another option is that the image of beginning a building project by laying a precious cornerstone suggests that God is about to transform Zion through judgment and begin a new covenant community that will experience his protection (see 4:3-6; 31:5; 33:20-24; 35:10).

[28:16]  ⁴ tn Heb “will not hurry,” i.e., act in panic.

[2:20]  ⁵ tn Grk “having been built.”

[2:20]  ⁶ sn Apostles and prophets. Because the prophets appear after the mention of the apostles and because they are linked together in 3:5 as recipients of revelation about the church, they are to be regarded not as Old Testament prophets, but as New Testament prophets.

[2:20]  ⁷ tn Grk “while Christ Jesus himself is” or “Christ Jesus himself being.”

[2:20]  ⁸ tn Or perhaps “capstone” (NAB). The meaning of ἀκρογωνιαῖος (akrogwniaio") is greatly debated. The meaning “capstone” is proposed by J. Jeremias (TDNT 1:792), but the most important text for this meaning (T. Sol. 22:7-23:4) is late and possibly not even an appropriate parallel. The only place ἀκρογωνιαῖος is used in the LXX is Isa 28:16, and there it clearly refers to a cornerstone that is part of a foundation. Furthermore, the imagery in this context has the building growing off the cornerstone upward, whereas if Christ were the capstone, he would not assume his position until the building was finished, which vv. 21-22 argue against.
