How many times is paraskeue used in the NT and which NT scripture relates it to the sixth day of the week. Let's take a look at that verse.
Luk 23:52 This man went unto Pilate, and begged the body of Jesus.
Luk 23:53 And he took it down, and wrapped it in linen, and laid it in a sepulchre that was hewn in stone, wherein never man before was laid.
Luk 23:54 And that day was the preparation[paraskeue], and the sabbath drew on.
It was the eve of the weekly Sabbath and the lights were already lit in the homes as was necessary before the Sabbath began.
Note the use of the word 'paraskeue', here in verse 54.
Why is it not also used in 23:56 and in 24:1?
Or why is 'hetoimazo' not used in all three places?
Luk 23:55 And the women also, which came with him from Galilee, followed after, and beheld the sepulchre, and how his body was laid.
The women followed to the tomb, just before sundown, the 'paraskeue' of the Sabbath.
Luk 23:56 And they returned, and prepared[2090-hetoimazo] spices and ointments; and rested the sabbath day according to the commandment.
Then they returned to wherever they were staying in Jerusalem and prepared[hetoimazo, not paraskeue] things to carry to the tomb after the weekly Sabbath was past. This also had to be done before sundown.
Luk 24:1 Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared[hetoimazo-2090], and certain others with them.
After the seventh day Sabbath was past, they were then free to return to the tomb to minister to the body the things that they had prepared before the Sabbath. This took place early in the morning on the first day of the week.
