“Servitude” in this verse is not referring to slavery like that which was served by the Hebrews in Egypt, but indentured servitude. This verse makes me think of what John the Baptist said in Matthew 3:7-10, “But when he saw many of the Pharisees and of the Sadducees, who came to be baptized, he said to them: Generation of vipers, who hath taught you to flee from the wrath that cometh? Bring forth the fruits therefore, that accord with repentance. And do not think, and say within yourselves, that Abraham is our father: for I say to you, that God is able of these tones to raise up children to Abraham. And lo, the ax is put to the root of trees. Every tree, therefore, which beareth not good fruit, is felled, and falleth into the fire.”
And the Yehudeans answered and said to him, "Did we not say well that a Samaritan you [are] and a devil you have?" Yeshua said to them, "There is no devil in me, but my father I do honor and you curse me!"- John 8:37-38
To be called a Samaritan and a demoniac in the same breath was quite a cutting insult. Most people would probably not only react by saying that they weren't possessed, but they would also say that they were not Samaritans either (if they weren't, of course). Unlike the religious elite of Jesus's day, Jesus was not against the Samaritans and he sought to restore them to the house of Israel by reaching out to them with the love of God. Through speaking the truth, Jesus brought glory to God the Father and when the Jewish authorities blasphemed against Christ, they also blasphemed against the Father who sent Him.
"And I do not seek my glory. There is He who seeks and judges. Truly, truly say I to you: that he who keeps my words, he will not see death forever." The Yehudeans said to him, "Now we know that a devil you have! Awraham died, and the prophets. And you say that "He who keeps my word will not taste death forever.' Why are you greater than our father Awraham who died, and the prophets who died? Who do you make yourself?"- John 8:39-42
Because they refused to accept Jesus's claims to be the Messiah, they could not see that He was indeed greater than any man who had ever appeared on earth. They behaved as if Jesus was exalting Himself.
Yeshua said to them, "If I glorify myself, my praise is not anything. My Father, who glorifies me, He whom you said, 'That is our God.' And you do not know him, but I know Him, and if I say that I do not know Him I would be a liar like yourselves. But I know Him, and His Word I keep."- John 8:43-44
Jesus tells them that He is not exalting Himself. He is telling them that His Father, the God who they believe they know, is the one who is exalting Him. Knowing God and keeping His commandments are joined at the hip, as these unbelieving Jews were not keeping the commandments of the Father, therefore they did not know Him. Jesus and those who accepted His Gospel were keeping the commandments of God through submitting themselves to the teachings of Christ and were fulfilling the Law of Moses as well.
"Awraham, your father, did long to see my day and he saw [it] and rejoiced." The Yehudeans said to him, "You are not yet fifty years old, yet Awraham you have seen?" Yeshua said to them, "Truly, truly, say I to you: that before Awraham existed, I was." And they took up rocks to stone him, and Yeshua hid and departed from the temple, and passed through their midst and left.- John 8:45-48
I find it interesting that Jesus refers to Abraham as their father and does not say "our father". In the Synoptic Gospels (see Matthew 22:41-46; Mark 12:35-37; Luke 20:41-44) Jesus implies that the Messiah is more than a man since He is referred to by David as "my Lord" (Peshitta Matthew says "Lord Yahweh"). The Jewish people understand that their ancestors are greater than they are, so in that context it is very strange indeed that the son of David, the Messiah, is said to be David's Lord (Lordship shows superiority). Jesus is saying that He is greater than Abraham here because He existed before Abraham, preexisting the incarnation as the God who created Abraham: Yahweh. The Greek manuscripts say "I AM", pointing back to the Divine Name revealed to Moses in Exodus 3:14. By saying that Abraham saw His day, He is saying that Abraham foresaw His coming. This was most likely in Genesis 22, when God told him that He would bless Abraham through his Seed (this Seed was Christ, as stated by Paul in Galatians 3:16) because he did not withhold his only begotten son Isaac. Abraham offering up his only son Isaac types out God offering His only Son Jesus. In this account, Isaac is not stated to protest to what Abraham was about to do. Jesus offered Himself freely as well. Abraham also knew that God was able to raise his son from the dead since he was the one through whom the promised Seed would come. Jesus also knew that God would raise Him from the dead and glorify Him for what He was going to do on the cross (John 2:18-22).
