'Abandoned' in the Bible

Then David said to him, "{To whom do you belong}, and from where [are] you? The young man said, "I am an Egyptian young man, a servant of an Amalekite man, but my master abandoned me because I became ill three days ago.

And when the men of Israel who [were] on the other side of the valley and [those] who were beyond the Jordan saw that the men of Israel had fled and that Saul and his sons were dead, they abandoned the towns and fled. Thus [the] Philistines came and lived in them.
