Command, Commandment
The term "commandment" in the Bible (mainly Heb. miswa [h"w.xim]; Gk. entole [ejntolhv]) refers to orders or adjurations given by authorities. The plural predominantly refers to Mosaic laws.
The commandments were for Israel's good ( Deut 10:13 ) since God's covenant love was lasting for those who kept them ( Exod 20:6 ; Deut 7:9 ). Obedience would result in prosperity, security, God's presence, longevity, the occupation of the land, a long dynasty, and blessings of all sorts ( Lev 26:3-13 ; Deuteronomy 5:29-6:2 Deuteronomy 5:17-18 ; 17:18-20 ; 28:1-14 ). Disobedience would result in terror, illness, oppression, infertility, exile, curses, and rebuke ( Lev 26:14-20 ; Deut 28:15-68 ; Psalm 119:21 ). Because Israel disobeyed, these threats came to pass historically. Purification (sin) offerings were required to atone for "inadvertent" violations of commandments (Lev. 4 Num 15:22-31 ).
God's commandments can be kept ( Deut 30:11-14 ). Abraham in essence kept God's "commands, decrees, and laws" ( Gen 26:5 ) even before these had been revealed through Moses, presumably via living by faith. The godly love, learn, and believe in God's commandments, for they contain precious, enlightening truth that makes one wise ( Psalm 19:8 ; Psalms 119:47-48 Psalms 119:66 Psalms 119:73 Psalms 119:98 Psalms 119:151 ). The wise follow godly commands as a guiding light ( Prov 6:23 ), and keep God's commandments in view of impending judgment.
The observant wore as a reminder tassels symbolic of keeping God's commandments ( Nu 15:38-40 ). Prosperity can cause one to forget them ( Deut 8:11-14 ), and adversity tests willingness to obey them ( Deut 8:2 ; Judges 3:4 ; cf. Job's suffering, Job 23:12 ). One must not allow even a miracle-working prophet to lead one away from them ( Deut 13:4 ).
Those who hope in salvation keep God's commandments ( Psalm 119:166 ), for keeping the commandments is essential for "righteousness, " that is, a right personal relationship with God.
Jesus taught that all the commands could be reduced to two based on the single principle of love ( Matt 22:36-40 ; Mark 12:28-31 ). Jesus kept the Sabbath command ( Luke 23:56 ), affirmed the keeping of others ( Matt 5:19 ; 19:17 ; Mark 10:19 ; Luke 18:20 ), and corrected misapplication of them based on rabbinic traditions ( Matthew 15:3 Matthew 15:6 ; Mark 7:8-9 ; 10:5 ). All that Jesus did, including his death and resurrection, were at the Father's commandment and served to further eternal life ( John 10:18 ; 12:49-50 ).
