Jehovah's punishment of Ephraim issued in His restoration.
In the day of restoration, Jehovah will become a crown of glory and a diadem of beauty to the remnant of His people (v. 5).
Jehovah will become a spirit of justice for him who sits in judgment and strength to those who turn away the battle at the gate (v. 6).
Jehovah's punishment over Ephraim's drunkards will also usher in the trustworthy Christ.
The trustworthy Christ is a stone laid by the Lord Jehovah in Zion as a foundation, a tested stone. Because Christ has been tested, He can be a foundation (v. 16a).
The trustworthy Christ is also a precious cornerstone as a foundation firmly established (v. 16b). In Matthew 21:42 the Lord Jesus refers to Himself as the cornerstone. Furthermore, both Paul and Peter speak of Christ as a cornerstone. In Ephesians 2:20 Paul says that in building up the two parts of God's building, the Jews and the Gentiles, Christ Jesus Himself is the cornerstone. In Acts 4:11 Peter says, "This is the stone which was despised by you, the builders, which has become the cornerstone." Later, in his first Epistle, Peter says, "To whom coming, a living stone, having been rejected by men, but with God chosen, held in honor" (2:4).
Isaiah 28:16c says that he who believes will not hasten away.
