TSK · Psalms 116:13

Yahweh assigned my portion and my cup. You made my lot secure.

Give thanks to Yahweh! Call on his name! Make his doings known among the peoples.

I will offer to you the sacrifice of thanksgiving, and will call on the name of Yahweh.

He received a cup, and when he had given thanks, he said, "Take this, and share it among yourselves,

The cup of blessing which we bless, isn't it a sharing of the blood of Christ? The bread which we break, isn't it a sharing of the body of Christ?

In the same way he also took the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink, in memory of me."
