LXX Psalm 108:21
19 Let it be to him as a garment which he puts on, and as a girdle with which he girds himself continually. 20 This is the dealing of the Lord with those who falsely accuse me, and of them that speak evil against my soul. 21 But thou, O Lord, Lord, deal mercifully with me, for thy name's sake: for thy mercy is good. 22 Deliver me, for I am poor and needy; and my heart is troubled within me. 23 I am removed as a shadow in its going down: I am tossed up and down like locusts.
Matthew 7:21
19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 So then, you will recognize them by their fruit. 21 “Not everyone who says to me, ‘Lord, Lord,’ will enter into the kingdom of heaven—only the one who does the will of my Father in heaven. 22 On that day, many will say to me, ‘Lord, Lord, didn’t we prophesy in your name, and cast out demons in your name, and do many powerful deeds in your name?’ 23 Then I will declare to them, ‘I never knew you. Go away from me, you lawbreakers!’
Notes and References
"... The dual address of God as “Lord, Lord,” though not unusual, serves still to amplify the intensity and directness of Eve’s prayer. The words, κύριε κύριε, translate in LXX הִוהְי יָנֹדֲא (e.g., Deuteronomy 3:24; 9:26; Judges 6:22; 16:28; Psalm 69:7; Amos 7:2, 5; Ezekiel 23:46) or יָנֹדֲא הִוהְי (LXX Psalm 108:21; 139:8; 140:8). In Matthew 7:21–22, Jesus says straightforwardly, “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father in heaven. On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many deeds of power in your name?’” In Luke 6:46, he asks simply, “Why do you call me ‘Lord, Lord,’ and do not do what I tell you?” And in the parable of the bridesmaids who arrive late, they say, “Lord, lord, open to us” (Matthew 25:11) ..."
