1 John 5:5-12 (Maharzan’s Literal Translation)

5 Who [and] is the one overcoming except the one believing that Jesus is the Son of God?  6 This is the one coming by water and blood, Jesus Christ, not by the water only but by the water and by the blood; and the Spirit is the one testifying, because the Spirit is the truth. 7 For three are the ones testifying, 8 the Spirit and the water and the blood, and ^{the} three ²in ³the ⁴one ¹are. 9 If we receive the testimony of men, the testimony of God is greater; because this is the testimony of God that he has testified concerning his Son. 10 The one believing in the Son of God has the testimony in himself, the one not believing ^{the} God has made him a liar, because he has not believed in the testimony which ^{the} God has testified concerning his Son. 11 And this is the testimony, that ^{the} God to us gave eternal life, and this ^{the} life is in his Son. 12 The one having the Son has ^{the} life; the one not having the Son of God does not have life.

Note:

5:7 For three are the ones testifying in the heavens: the Father, the Word, and the Holy Spirit and these three are one.

5:8 And three are the ones testifying in {the} earth: the Spirit and the water and the blood, and ^{the} three ²in ³the ⁴one ¹are.
