'Offspring' in the Bible

And Eli would bless Elkanah and his wife, and he said, "May Yahweh give you an offspring from this woman in place of the petitioned [one] that she requested from Yahweh." Then they went to their home.

Jonathan said to David, "Go in peace, because we have sworn, the two of us, [an oath] in the name of Yahweh, saying, "Yahweh will be between me and you, and between my offspring and your offspring forever." Then he got up and left, and Jonathan went into the city.
