Charles H. Spurgeon on Psalms 116:13

I will take the cup of salvation. —It may probably allude to the libation offering, Nu 28:7; for the three last verses seem to intimate that the Psalmist was now at the temple, offering the meat offering, drink offering, and sacrifices to the Lord. "Cup" is often used by the Hebrews to denote plenty or abundance. So, "the cup of trembling, "an abundance of misery; "the cup of salvation, "an abundance of happiness. Adam Clarke.
