The chapter opens with a cry: everyone who thirsts, come to the waters; and he who has no money, come, buy and eat. Buy wine and milk without money and without price. He asks why they spend money on what is not bread and their labor on what does not satisfy. He invites them to listen so that they may eat what is good and delight in rich food. Incline your ear and come, listen that you may live. The Lord will make with them an everlasting covenant, the sure mercies of David.
The Lord made David a witness to the peoples, a leader and commander. You will call a nation you do not know, and a nation that did not know you will run to you because of the Lord your God, the Holy One of Israel, who has glorified you. Verses 6 and 7 call: seek the Lord while he may be found, call upon him while he is near. Let the wicked forsake his way and the unrighteous man his thoughts, and let him return to the Lord, who will have compassion on him, and to our God, for he will abundantly pardon.
Verses 8 and 9 explain the basis of this pardon: my thoughts are not your thoughts, neither are your ways my ways, for as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. Then God's word is compared to the rain and the snow that come down from heaven, water the earth and make it bring forth and sprout, giving seed to the sower and bread to the eater; so is my word that goes out from my mouth, it will not return empty but will accomplish what I purpose. The chapter ends in joy: you will go out in joy and be led forth in peace, the mountains and the hills will break forth into singing and all the trees of the field will clap their hands. Instead of the thorn the cypress will grow, instead of the brier the myrtle; it will be a name for the Lord, an everlasting sign that will not be cut off.
