Albert Barnes Commentary Matthew 23:11-12

"But he that is greatest among you shall be your servant. And whosoever shall exalt himself shall be humbled; and whosoever shall humble himself shall be exalted." — Matthew 23:11-12 (ASV)

He that shall humble himself, etc. God will exalt or honour him who is humble, and who seeks a lowly place among men. That is true religion, and God will and God will reward it.
