Here's the rewritten verse in simple modern English: "Now, tell your son Lamech that the child who has been born is truly his son. Name him Noah. He will be left to you, and he and his children will be saved from the destruction that will come to the earth because of all the sin and wrongdoing that will happen in his time."
And now make known to thy son Lamech that he who has been born is in truth his son, and call his name Noah; for he shall be left to you, and he and his sons shall be saved from the destruction, which shall come upon the earth on account of all the sin and all the unrighteousness, which shall be consummated on the earth in his days.
