'Spared' in the Bible

And there came a traveller to the rich man, and he spared to take of his own flock and of his own herd, to dress for the wayfaring man that had come to him; and he took the poor man's lamb, and dressed it for the man that had come to him.

But the king spared Mephibosheth, the son of Jonathan the son of Saul, because of Jehovah's oath that was between them, between David and Jonathan the son of Saul.
