Charles H. Spurgeon on Psalms 116:13

Cup of salvation. Yeshuoth:Ps 18:50 28:8 53:6. The cup of salvation, symbolized by the eucharistic cup of the Passover Supper. —Zion that had drunk of the "cup of trembling" (Isa 51:17, 22) might now rise and drink of the cup of salvation. To the church these words have had a yet deeper significance added to them by Mt 26:27. Jesus, on that Passover night, drank of the bitter wine of God's wrath, that he might refill the cup with joy and health for his people. William Kay.

Verses 13-14, 17-19. A fit mode of expressing our thanks to God is by solemn acts of worship, secret, social, and public. "The closet will be the first place where the heart will delight in pouring forth its lively joys; thence the feeling will extend to the family altar: and thence again it will proceed to the sanctuary of the Most High." (J. Morison). To every man God has sent a large supply of benefits, and nothing but perverseness can deny to him the praise of our lips. William, S. Plumer.
