When they arrived at the place God had pointed out to him, Abraham built an altar there, and arranged the wood. Then he bound his son Isaac and put him on the altar on top of the wood. Abraham stretched out his hand and seized the knife to kill his son.

But the angel of the Lord called to him from heaven. ‘Abraham, Abraham’ he said. ‘I am here’ he replied. ‘Do not raise your hand against the boy’ the angel said. ‘Do not harm him, for now I know you fear God. You have not refused me your son, your only son.’ Then looking up, Abraham saw a ram caught by its horns in a bush. Abraham took the ram and offered it as a burnt-offering in place of his son.

Abraham called this place ‘The Lord Provides’, and hence the saying today: On the mountain the Lord provides.

The angel of the Lord called Abraham a second time from heaven. ‘I swear by my own self – it is the Lord who speaks – because you have done this, because you have not refused me your son, your only son, I will shower blessings on you, I will make your descendants as many as the stars of heaven and the grains of sand on the seashore. Your descendants shall gain possession of the gates of their enemies. All the nations of the earth shall bless themselves by your descendants, as a reward for your obedience.’

Here I am, Lord! I come to do your will.

You do not ask for sacrifice and offerings, 
  but an open ear.
You do not ask for holocaust and victim.
  Instead, here am I.

Here I am, Lord! I come to do your will.

In the scroll of the book it stands written 
  that I should do your will.
My God, I delight in your law 
  in the depth of my heart.

Here I am, Lord! I come to do your will.

Your justice I have proclaimed 
  in the great assembly.
My lips I have not sealed;
you know it, O Lord.

Here I am, Lord! I come to do your will.

O let there be rejoicing and gladness 
  for all who seek you.
Let them ever say: ‘The Lord is great’, 
  who love your saving help.

Here I am, Lord! I come to do your will.

Alleluia, alleluia!
Christ became obedient for us unto death, even death on a cross.
Therefore God has exalted him and given him a name which is above every name.
Alleluia!
