[12] How long was Jesus dead for?

50 Again Jesus cried out with a loud voice, and yielded up [his] spirit. (NWT)
50 And Jesus having again cried with a great voice, yielded the spirit; (YLT)
51 And, look! the curtain of the sanctuary was rent in 2, from top to bottom, and the earth quaked, and the rock-masses were split. (NWT)
51 and lo, the vail of the sanctuary was rent in two from top unto bottom, and the earth did quake, and the rocks were rent, (YLT)
52 And the memorial tombs were opened and many bodies of the holy ones that had fallen asleep were raised up, (NWT)
52 and the tombs were opened, and many bodies of the saints who have fallen asleep, arose, (YLT)
53 and persons, coming out from among the memorial tombs along with his being raised up, entered into the holy city, and they became visible to many people. (Matthew 27 NWT - revised)
53 and having come forth out of the tombs along with his rising, they went into the holy city, and appeared to many. (Matthew 27 YLT)

44 Well, by now it was about the 6th hour, and yet a darkness fell over all the earth until the 9th hour, (NWT)
44 And was already as if hour sixth and darkness occurred upon whole the earth until hour ninth (KIT)
45 because the sunlight failed; then the curtain of the sanctuary was rent down the middle. (NWT)
45 of the sun leaving out, was split but the curtain of the divine habitation middle. (KIT)
46 And Jesus called with a loud voice and said: Father, into your hands [plural] I entrust my spirit. When he had said this, he expired. (Luke 23 NWT)
46 And having sounded to voice great the Jesus said Father, into hands [plural] of you I am placing beside the spirit of me; this but having said he expired. (Luke 23 KIT)

5 Into your hand [singular] I entrust my spirit. You have redeemed me, Oh Jehovah the God of truth. (Psalms 31 NWT)
5 ^d.y"B. dyqip.a; yxiWr ht'ydiP' ytiAa hw"hy> lae tm,a/ (Psalms 31 WLC)

40 For just as Jonah was in the belly of the huge fish 3 days and 3 nights, so the Son of man will be in the heart of the earth 3 days and 3 nights. (Matthew 12 NWT)

The thing is that one cannot be in the heart of the earth if one is asleep in the first death. So Jesus must have been resurrected for some part of the night Nisan15 in order that he was in the heart of the earth for 3 days and for 3 nights (i.e. for parts thereof).

Now in the Psalms we read that he is going to say: Into your hand [singular] I entrust my spirit. Yet when the fulfilment came he actually said: Into your hands [plural] I entrust my spirit. So whereas David remained in the first death for 5 hours, Jesus remained in it for 10 hours. Then he gave his spirit body, his angelic body, to God as a ransom for Adam on 33Nisan16 - see Intro28.

For the counting dimension of the code tells us that he entrusted his spirit to God for two hands after his human death. That is 10x. Which are normally days or months or years or prophetic times. But none of these apply here since we know he was resurrected within 48 hours and in fact on the night of 33Nisan15 so within 15 hours actually. Therefore these 10x must be 10 hours. Jesus used the unit of time in John 11 saying...

9 Jesus answered: There are 12 hours of daylight, are there not? If anyone walks in daylight he does not bump against anything, because he sees the light of this world. (John 11 NWT)

So we deduce that Jesus was in the first death, for 10 hours. He took a 10 hour nap and was resurrected in the seventh hour of 33Nisan15. The reason for this we think is that those who had been born again and had died and were buried in tombs around Jerusalem were resurrected first as humans as described in Matthew 27 and then raptured into angels. These guys could not become angels until Jesus had made his sacrifice. And since he was to be the firstborn from the dead he had to be resurrected before they could be...

18 and he is the head of the body, the congregation. He is the beginning, the firstborn from the dead [the owner of the firstborn angel rights which we received pursuant to his agreement with Satan after his sacrifice], that he might become the one who is first in all things; (Colossians 1 NWT)
5 and from Jesus Christ, the Faithful Witness, The firstborn from the dead, and The Ruler of the kings of the earth. To him that loves us and that loosed us from our sins by means of his own blood -- (Revelation 1 NWT)

Now in order that people did not see the kingdom manifestation and therefore have to be born again instantly, the resurrection from the graves would have occurred once darkness had truly set in. So the 7th hour of the night would be fine. Hence Jesus was resurrected at that time, after his 10 hour snooze.
