Hardly a misinterpretation, Jesus
confirmed their interpretation.
John 10:27-33
27 My sheep hear my voice, and I know them, and they follow me:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30 I and my Father are one.
31 Then the Jews took up stones again to stone him.
32 Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?
33 The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.
Help me out here and continue reading. You'll arrive at a place where Jesus answers and says, "Is it not written in your law...?" Where does he quote from, and how might that possibly be applicable to the situation at hand?
Psa 82:1-8 KJV
(1) <A Psalm of Asaph.>
God standeth in the congregation of the mighty; he judgeth among the gods.
(2) How long will ye judge unjustly, and accept the persons of the wicked? Selah.
(3) Defend the poor and fatherless: do justice to the afflicted and needy.
(4) Deliver the poor and needy: rid them out of the hand of the wicked.
(5) They know not, neither will they understand; they walk on in darkness: all the foundations of the earth are out of course.
(6)
I have said, Ye are gods; and
all of you are children of the most High.
(7) But ye shall die like men, and fall like one of the princes.
(8)
Arise, O God, judge the earth: for thou shalt inherit all nations.
