From the tree (apo tou xulou). Not here strictly a tree, but wood as already in Act 5:30; Act 10:29 and later in Gal 3:13. Strictly speaking, it was Joseph of Arimathea and Nicodemus who took the body of Jesus down from the cross, though the Jews had asked Pilate to have the bones of Jesus broken that his body should not remain on the cross during the Sabbath (Joh 19:31). Paul does not distinguish the details here.
Laid (ethēkan). First (kappa) aorist active indicative third plural of tithēmi in place of ethesan the usual second aorist active plural form.
Tomb (mnēmeion). Memorial, common in the Gospels.
