SEV Biblia, Chapter 21:12
Y David puso en su corazón estas palabras, y tuvo gran temor de Aquis rey de Gat.
John Gill's Bible Commentary
Ver. 12. And David laid up these words in his heart , etc.] Pondered upon them, and thought them over in his mind, finding that he was known, and his character also, and considered with himself what might be the consequence of this: and was sore afraid of Achish the king of Gath ; lest he should be set against him, and be prevailed upon by his servants to take away his life, or deliver him up into the hands of Saul.
Matthew Henry Commentary
Verses 10-15 - God's persecuted people have often found better usage from Philistine than from Israelites. David had reason to put confidence in Achish, ye he began to be afraid. His conduct was degrading, and discovere wavering in his faith and courage. The more simply we depend on God and obey him, the more comfortably and surely we shall walk throug this troublesome world __________________________________________________________________
