Psalm 110:1
1 A psalm of David. Here is the Lord’s proclamation to my lord: “Sit down at my right hand until I make your enemies your footstool.” 2 The Lord extends your dominion from Zion. Rule in the midst of your enemies. 3 Your people willingly follow you when you go into battle. On the holy hills at sunrise the dew of your youth belongs to you. 4 The Lord makes this promise on oath and will not revoke it: “You are an eternal priest after the pattern of Melchizedek.” 5 O Lord, at your right hand he strikes down kings in the day he unleashes his anger.
1 Corinthians 15:25
23 But each in his own order: Christ, the firstfruits; then when Christ comes, those who belong to him. 24 Then comes the end, when he hands over the kingdom to God the Father, when he has brought to an end all rule and all authority and power. 25 For he must reign until he has put all his enemies under his feet. 26 The last enemy to be eliminated is death. 27 For he has put everything in subjection under his feet. But when it says “everything” has been put in subjection, it is clear that this does not include the one who put everything in subjection to him.
Notes and References
"... Seeing Jesus on the heavenly throne is a significant pointer to how the earliest Christians viewed Jesus, beginning from Peter at Pentecost ... 1 Corinthians 15:25-27 brings together Psalm 110:1 and Psalm 8:6. Williams considers the reference to Psalm 110 to be an allusion rather than a citation. There is no introductory formula, and only the words ‘enemy’ and ‘foot’ correspond directly to Psalm 110:1. “God’s right hand” is not mentioned explicitly. Psalm 8 is more clearly a citation. It is followed by the comment: “Now when it says”, although once again there are textual differences between Psalm 8:6 and 1 Corinthians 15:27 ..."
