C. F. Keil and Franz Delitzsch on 2 Samuel 1:4

2Sa 1:4

David’s inquiry, “How did the thing happen?” refers to the statement made by the messenger, that he had escaped from the army of Israel. In the answer, אשׁר serves, like כּי in other passages, merely to introduce the words that follow, like our namely (vid., Ewald, §338, b.). “The people fled from the fight; and not only have many of the people fallen, but Saul and Jonathan his son are also dead.” וגם ... וגם:not only ... but also.
