1 Chronicles 11:23
And he slew an Egyptian, a man of great stature, five cubits high; and in the Egyptian’s hand was a spear like a weaver’s beam; and he went down to him with a staff, and plucked the spear out of the Egyptian’s hand, and slew him with his own spear.
1 Chronicles 11:23 belongs to the account of the kingdom of Judah that parallels the last part of Samuel and comes from the prosperous years of David's reign. It is part of the parallel account of David's rise to the throne and the events surrounding his reign. Apart from genealogies, it is to be compared with the parallel record in Samuel.
The verse records the exploit of Benaiah, one of David's truly mighty men, a man of great valor, who slew a giant Egyptian with the Egyptian's own spear. Benaiah was a priest serving among David's military commanders, showing that some priests served as warriors. The passage is to be studied for why such men were mighty, for David's work and the division of his armies, for his virtues and mistakes, and for God's mercy and guidance.
