Jonathan Isaiah 43:5
1 But now thus saith the Lord that created thee, O Jacob, and He that formed thee, O Israel, Fear not, for I have redeemed thee, I have called thee who art mine by thy name. 2 For at first when ye did pass the Red sea my Word was your support. Pharaoh and the Egyptians, who were as many as the waters of the river, did not prevail against you. And again, when ye came amongst nations, who were as mighty as fire, they did not prevail against you; and kingdoms, which were strong as a flame, did not destroy you; 3 Because I am the Lord thy God, the Holy One of Israel, thy Saviour: I gave Egypt in ex change for thee, Ethiopia, and Seba, in thy stead. 4 Ever since I loved thee, thou wast precious; yea, I loved thee dearly, and I gave nations instead of thee, and kingdoms for thy soul. 5 Fear not, for my Word shall be thy support; I will bring thy children from the east, I will bring together thy captivity from the west. 6 I will say to the north, Bring; and to the south, Keep not back: bring my sons from afar, and the captivity of my people from the ends of the earth.
1 John 2:1
1 (My little children, I am writing these things to you so that you may not sin.) But if anyone does sin, we have an advocate with the Father, Jesus Christ the Righteous One, 2 and he himself is the atoning sacrifice for our sins, and not only for our sins but also for the whole world. 3 Now by this we know that we have come to know God: if we keep his commandments. 4 The one who says “I have come to know God” and yet does not keep his commandments is a liar, and the truth is not in such a person. 5 But whoever obeys his word, truly in this person the love of God has been perfected. By this we know that we are in him.
Notes and References
"... John 14:16 suggests the possibility, via Targum terminology, that ‘I am with you’ is divine speech. Jesus says, ‘I will ask the Father, and he will give you another Helper, that he might be with you forever.’ ‘Another’ suggests that the first Helper is Jesus himself, which many view as being confirmed by 1 John 2:1, where this same word (Paraclete) is used: ‘And if anyone sins, we have a Helper with the Father, Jesus Christ the righteous.’ This passage, of course, is just a few verses before John uses the language of Targum Isaiah 43:10, 25, as we saw in section 2; and Targum Isaiah 43:2, 5 has language about the divine Word being for the help of his people (for the Masoretic text ‘I am/will be with you’). Could Jesus be mixing Masoretic and Targum language in John 14:16, obliquely referring to himself as Helper (who has been with them) by promising another Helper, then using Masoretic language behind the Targum language, ‘that he might be with you forever’? It would be difficult to prove that the Paraclete title is related to the Targums, but when Targum connections continue to add up, the plausibility increases ..."
