Charles Ellicott Commentary Proverbs 18:24

"He that maketh many friends [doeth it] to his own destruction; But there is a friend that sticketh closer than a brother." — Proverbs 18:24 (ASV)

A man that hath friends must shew himself friendly. —Rather, a man of many friends will suffer loss, for he will impoverish himself by constant hospitality, and in trouble they will desert him (Psalms 41:9); but “there is a friend,” one in a thousand, “that sticketh closer than a brother.” .
