(those) of the (his own) house(-hold)

Dictionary of Biblical Words:

is used in Scripture, not only to designate the sanctuary in Israel, but His dwelling place now, His assembly in its earthly aspect where He abides by or in the Spirit sent down from heaven (1 Tim. 3:1515But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth. (1 Timothy 3:15)); Christ’s house (Heb. 3:66But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end. (Hebrews 3:6)). Compare Math. 16:18; 1 Cor 3:9-169For we are laborers together with God: ye are God's husbandry, ye are God's building. 10According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon. 11For other foundation can no man lay than that is laid, which is Jesus Christ. 12Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 13Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. 14If any man's work abide which he hath built thereupon, he shall receive a reward. 15If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. 16Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? (1 Corinthians 3:9‑16); 2 Cor. 5:1717Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. (2 Corinthians 5:17), Eph. 2:2222In whom ye also are builded together for an habitation of God through the Spirit. (Ephesians 2:22), where it is called His “temple” and “habitation,” remembering, however, that what the Lord builds is good and stands, what man builds may be more or less evil. It is the scene of profession though at first real, as early in the Acta of the Apostles.

Concise Bible Dictionary:

Those who dwell in a house under one head, including the wife and children, and embracing servants who were usually slaves (Gen. 15:2-32And Abram said, Lord God, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus? 3And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir. (Genesis 15:2‑3); Luke 12:4242And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? (Luke 12:42); Acts 10:77And when the angel which spake unto Cornelius was departed, he called two of his household servants, and a devout soldier of them that waited on him continually; (Acts 10:7); Phil. 4:2222All the saints salute you, chiefly they that are of Caesar's household. (Philippians 4:22)). We read of the baptism of whole households (Acts 16:1515And when she was baptized, and her household, she besought us, saying, If ye have judged me to be faithful to the Lord, come into my house, and abide there. And she constrained us. (Acts 16:15); 1 Cor. 1:1616And I baptized also the household of Stephanas: besides, I know not whether I baptized any other. (1 Corinthians 1:16)). The Lord speaks of His disciples as His household (Matt. 10:2525It is enough for the disciple that he be as his master, and the servant as his lord. If they have called the master of the house Beelzebub, how much more shall they call them of his household? (Matthew 10:25)); and saints are called the “household of faith,” and the “household of God” (Gal. 6:1010As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith. (Galatians 6:10); Eph. 2:1919Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; (Ephesians 2:19)).
