Psalm 116:12-18
12What will I give to Yahweh for all his benefits toward me?
13I will take the cup of salvation, and call on Yahweh’s name.
14I will pay my vows to Yahweh,
yes, in the presence of all his people.
15Precious in Yahweh’s sight is the death of his saints.
16Yahweh, truly I am your servant.
I am your servant, the son of your servant.
You have freed me from my chains.
17I will offer to you the sacrifice of thanksgiving,
and will call on Yahweh’s name.
18I will pay my vows to Yahweh,
yes, in the presence of all his people,

Exodus 24:3-8
3 Therefore, Moses went and explained to the people all the words of the Lord, as well as the judgments. And all the people responded with one voice: "We will do all the words of the Lord, which he has spoken."
4 Then Moses wrote all the words of the Lord. And rising up in the morning, he built an altar at the base of the mountain, with twelve titles according to the twelve tribes of Israel.
5 And he sent youths from the sons of Israel, and they offered holocausts, and they immolated calves as peace-offerings to the Lord.
6 And so Moses took one half part of the blood, and he put it into bowls. Then the remaining part he poured over the altar.
7 And taking up the book of the covenant, he read it in the hearing of the people, who said: "All that the Lord has spoken, we will do, and we will be obedient."
8 In truth, taking up the blood, he sprinkled it on the people, and he said, "This is the blood of the covenant, which the Lord has formed with you concerning all these words."
