Albert Barnes Commentary John 10:31

"The Jews took up stones again to stone him." — John 10:31 (ASV)

The Jews took up stones. Stoning was the punishment of a blasphemer (Leviticus 24:14–16). They considered him guilty of blasphemy because he made himself equal with God (John 10:33).

Again. They had before plotted against his life (John 5:16, 18) and once at least they had taken up stones to destroy him (John 8:59).
