'Spared' in the Bible

A traveler came to the rich man, and he spared to take of his own flock and of his own herd, to dress for the wayfaring man who had come to him, but took the poor man's lamb, and dressed it for the man who had come to him."

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