Why use ten when two commandments are enough (Matthew 22:35-40)? So also Stalin:
The first commandment: Don’t allow yourselves to be provoked by the counter-revolutionaries; arm yourselves with restraint and self-control; save your strength for the coming struggle; permit no premature actions.
The second commandment: Rally more closely around our Party; close your ranks in face of the assault of our innumerable enemies; keep the banner flying; encourage the weak, rally the stragglers and enlighten the unawakened. (Collected Works, vol. 3, p. 113)
