'Blessing' in the Bible

So may it please you to bless the household of your servant, so that it might remain forever in your presence, because you, Lord GOD, have spoken, and from your blessing may the household of your servant be blessed forever."

But King David declined, saying to Absalom, "No, my son, we won't all go, since that would be too much trouble for you." Although Absalom begged David, he would not go, even though he did give his blessing.
