brotherly love (kindness), love of the brethren

“Brethren” From Concise Bible Dictionary:

Besides the literal meaning of the term, it was used for persons morally or nationally associated together; also for those who formed the Jewish nation (Acts 2:29,3729Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. (Acts 2:29)
37Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? (Acts 2:37)
where the expression “Men and brethren” should be translated simply “Brethren”; Rom. 9:33For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh: (Romans 9:3)). It was applied by the Lord to His disciples: “Go to my brethren, and say unto them, I ascend to my Father, and your Father; and to my God, and your God” (John 20:1717Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God. (John 20:17)). “He is not ashamed to call them brethren” (Heb. 2:1111For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren, (Hebrews 2:11); Psa. 22:2222I will declare thy name unto my brethren: in the midst of the congregation will I praise thee. (Psalm 22:22)). The Lord has placed the Christian in His own relationship as man with His Father and God, and “He that sanctifieth and they who are sanctified are all of one.” In accordance with this the saints are constantly addressed in the Epistles as “brethren,” and referred to in the Acts as “the brethren.”

“5. Covetousness. Love of Money” From Concise Bible Dictionary:

Both πλευνεξία and φιλαργυρία -ρος refer to covetousness, but there appears to be a marked distinction between them. πλεονεξία (from πλέον, and ἔχω ‘to have more') is not confined to money, and is often connected with open wickedness, the force of the word being ‘desiring more (than is necessary),' and hence ‘an over-reaching to get,' and is thus applied to the lusts of the flesh, Rom. 1:2929Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, (Romans 1:29); Eph. 4:1919Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness. (Ephesians 4:19), where it is translated ‘greediness'; v. 3; &c. It is declared to be idolatry, Col. 3:55Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: (Colossians 3:5).
On the other hand, φιλαργυρία (from φίλος and ἄργυρος) literally ‘love of money,' is the miser's sin, and may be indulged in with a profession of religion. Thus in Luke 16:1414And the Pharisees also, who were covetous, heard all these things: and they derided him. (Luke 16:14) it is applied to the Pharisees, and in 2 Tim. 3:22For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, (2 Timothy 3:2) to those who had a form of godliness, but denied the power thereof. This love of money is a root of all kinds of evil, 1 Tim. 6:1010For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows. (1 Timothy 6:10), and those who go after it are liable to wander away from the faith, and to pierce themselves through with many sorrows.
