John Wesley on 1 Samuel 2:10

Exalt - Increase, or advance the strength. Of his anointed - Of his king. This may respect Christ, the singular anointed one of God, and the special king of his people. In this sense also, the Lord shall judge the ends of the earth: David's victories and dominions reached far. But God will give to the Son of David, the uttermost parts of the earth for his possession. And he will give strength unto his king, for the accomplishing his great undertaking, and exalt the horn, of the power and honour of his anointed, till he hath put all his enemies under his feet.
