Christians, what type of stones should I use when stoning my unruly child in accordance with the bible ?

Question

"And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard. And all the men of his city shall stone him with stones, that he die"

(Deuteronomy 21:20-21).

Answer 1

Such arrangement evidently had reference to a son beyond the age of what is usually considered a young child, for this one the Scriptures describe as “a glutton and a drunkard.” (De 21:18-21)
The behaviour here calling for the punishment you mention is no trivial thing, but rather serious repeated belligerence. Such penalties underscored the gravity of breaking divine law. One striking his father or mother, or calling down evil upon his parents, a deliberate, unrepentant wrongdoer, was put to death. The reason for such strong measures was that the nation might clear away what was bad from their midst and so that “all Israel [would] hear and indeed become afraid.” Therefore, any tendency in the nation toward juvenile delinquency or disrespect of parental authority would be greatly retarded by the punishment inflicted upon such offenders.—Ex 21:15, 17
In fact, the first commandment with a promise was the fifth of the Ten Commandments: “Honor your father and your mother, . . . in order that your days may prove long and it may go well with you on the ground that Jehovah your God is giving you.”—De 5:16; Eph 6:2, 3.

Answer 2

As we are in the "New Testament Times" it is not necessary to pursue this line of thought anymore.

Answer 3

better direct that question to the Jewish that may still "live according to the law" ..as for us we are under GRACE not the law, so we do not stone our children.
