Concise Bible Dictionary:

Various Hebrew words are so translated, having regard to the different uses to which the cup was put. It is frequently used for that which the cup contains, causing either joy or sorrow, as “I will take the cup of salvation and call upon the name of the Lord” (Psa. 116:1313I will take the cup of salvation, and call upon the name of the Lord. (Psalm 116:13)). “In the hand of the Lord there is a cup, and the wine is red....the dregs thereof, all the wicked of the earth shall wring them out and drink them” (Psa. 75:88For in the hand of the Lord there is a cup, and the wine is red; it is full of mixture; and he poureth out of the same: but the dregs thereof, all the wicked of the earth shall wring them out, and drink them. (Psalm 75:8); compare Rev. 14:1010The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: (Revelation 14:10); Rev. 16:1919And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath. (Revelation 16:19)). And so in many other instances; and especially in that of the cup of which the Lord Jesus drank when bearing sin (Matt. 26:27,39,4227And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; (Matthew 26:27)
39And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. (Matthew 26:39)
42He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done. (Matthew 26:42); John 18:1111Then said Jesus unto Peter, Put up thy sword into the sheath: the cup which my Father hath given me, shall I not drink it? (John 18:11)). In the Lord’s Supper the “cup” is put for the wine which was an emblem of the blood of Christ (1 Cor. 10:16,2116The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? (1 Corinthians 10:16)
21Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils. (1 Corinthians 10:21); 1 Cor. 11:25-2825After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. 26For as often as ye eat this bread, and drink this cup, ye do show the Lord's death till he come. 27Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. 28But let a man examine himself, and so let him eat of that bread, and drink of that cup. (1 Corinthians 11:25‑28)).
