Let us now put these conclusions in
simple order. Jesus was crucified on Passover day (the 14th of Abib) and was buried as the “high day” sabbath (the 15th of Abib) “drew on”. (See John 19:31 and John 19:14 and 42, and Luke 23:50-54). When that high day “sabbath was past” the women bought and prepared the spices. (Compare Mark 16:1 with Luke 23:56, first clause).
Thus, the spices were boughton the 16th of Abib. This was followed
by the 17th of Abib, which was "the sabbath day according to the commandment," on which the women
rested.
"In the end of" this, the two Marys came to see the sepulchre and found that Jesus had risen. (Compare Luke 23:56, last clause, with Matthew 28:1-6.) Therefore, as the 17th of Abib was "the sabbath day according to the commandment", now called Saturday; the 16th of Abib (when the spices were bought) was Friday; the 15th of Abib (the high day sabbath) was Thursday; and the 14th of Abib (Passover day) was Wednesday.
Jesus,therefore, was buried in the end of Wednesday, as Thursday, the "high day" sabbath drew on, and rose in the end of Saturday, the 7th day, as the first day also drew on, having been in the tomb exactly three days and three nights, or seventy-two hours. The four gospels, therefore, are in complete harmony on the question of the three days and three nights, and Mark and Luke are in perfect accord as to when the spiceswere bought.
