As I have mentioned before, stoning was unknown before the 18th century and the heaviest punishment given for apostasy was a fine.
"Stoning was a popular biblical use of stones (Ex 8:26; 17:4; Lev 20:2, 27; 24:14-23; Num 14:10; 15:35; Deu 13:10; 17:5; 21:21; 22:21-24; Josh 7:25-26; 1 Ki 5:15; 6:7, 18, 36; 12:18; 2 Ki 21:10-13; 2 Chr 10:18; 24:21; Lam 3:53; Ezek 16:40; 23:47; Mat 23:37; Mk 12:4; Lk 13:34; 20:6; John 8:7, 59; 10:31-33; 11:8; Acts 14:5). This was the official method of execution prescribed by the Law of Moses. Famous victims of stoning include Achan, Naboth, Stephen, and Paul (Josh 7:25; 1 Ki 21:13-16; Acts 7:59; 14:19; 2 Cor 11:25). The Israelites also threatened to stone Moses, Joshua, and Jesus. Indeed, our Lord called Jerusalem "the one who kills the prophets and stones those who are sent to her" (Mt 23:37; Lk 13:34)."
