Charles Spurgeon Commentary 1 Samuel 30:11-13

"And they found an Egyptian in the field, and brought him to David, and gave him bread, and he did eat; and they gave him water to drink. And they gave him a piece of a cake of figs, and two clusters of raisins: and when he had eaten, his spirit came again to him; for he had eaten no bread, nor drunk any water, three days and three nights. And David said unto him, To whom belongest thou? and whence art thou? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days ago I fell sick." — 1 Samuel 30:11-13 (ASV)

And they found an Egyptian in the field, and brought him to David, and gave him bread, and he ate; and they made him drink water; And they gave him a piece of a cake of figs, and two clusters of raisins: and when he had eaten, his spirit came again to him; for he had eaten no bread, nor drunk any water, three days and three nights. And David said to him, To whom do you belong? And where are you from? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days ago I fell sick.

Shame on his master, I say, and yet there are some who stop their men's wages as soon as they get a little ill! Shame on them, I say. It might be fit for an Amalekite to do this, but certainly not for an Israelite. So this young Egyptian tells David all about what they had done; and David follows them, strikes them with the sword, takes away their plunder, and, moreover, gets a great spoil to himself, and so the Lord hears the voice of David. Now Abraham's servant and David were men in difficulties similar to ours, but they asked guidance of God and received it; let us be sure in every time of difficulty to do the same.
