'Offspring' in the Bible

And every year Eli gave Elkanah and his wife a blessing, saying, May the Lord give you offspring by this woman in exchange for the child you have given to the Lord. And they went back to their house.

But one man of your family will not be cut off by my hand, and his eyes will be made dark, and grief will be in his heart: and all the offspring of your family will come to their end by the sword of men.
