Isaiah 55:4-12
bible
4 Behold, I have given him for a witness to the peoples, a leader and commander to the peoples. 5 Behold, you shall call a nation that you don't know; and a nation that didn't know you shall run to you, because of Yahweh your God, and for the Holy One of Israel; for he has glorified you. 6 Seek you Yahweh while he may be found; call you on him while he is near: 7 let the wicked forsake his way, and the unrighteous man his thoughts; and let him return to Yahweh, and he will have mercy on him; and to our God, for he will abundantly pardon. 8 For my thoughts are not your thoughts, neither are your ways my ways, says Yahweh. 9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts. 10 For as the rain comes down and the snow from the sky, and doesn't return there, but waters the earth, and makes it bring forth and bud, and gives seed to the sower and bread to the eater; 11 so shall my word be that goes forth out of my mouth: it shall not return to me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. 12 For you shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing; and all the trees of the fields shall clap their hands.
