We are not given any specific data or comment about the nature of the blasphemy because it is not necessary to know these things. It was very obviously a flagrant offense and one that struck at the authority and majesty of the covenant Lord... [It] was a denial of God and His covenant, a declaration that belief in God and His covenant with Israel and also His providential care are nonsense. In some form it was a challenge, with contempt and a denial of the authority of the covenant God of Israel.
