Every man Jesus tasted death for was of the election of grace,
For it is plainly stated Heb 2:9
9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
The Grace of God is limited to a remnant according to election Rom 11:5-7
5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded.
Plainly He tasted death for all of the election of Grace !
Christs death was in pursuant to the fulfilling of the Covenant of Grace, an Everlasting Covenant established before the world began, and a remnant seed was given Grace in Christ who should be saved by Him 2 Tim 1:9
9 Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
Heb 13:20
20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant,
This proves His death was in accordance with a covenant and therefore for a covenant people !
