{But if it is of God} (ei de ek theou estin). The second
alternative is a condition of the first class, determined as
fulfilled, ei with the present indicative. By the use of this
idiom Gamaliel does put the case more strongly in favor of the
apostles than against them. This condition _assumes_ that the
thing is so without _affirming_ it to be true. On the basis of
this alternative Gamaliel warns the Sanhedrin that they cannot
"overthrow" (katalusai) these men for they in that case must
"overthrow" God, {lest haply ye be found} (m(8820)pote--hureth(8874)e,
negative purpose with first aorist passive subjunctive) {even to
be fighting against God} (kai theomachoi, late adjective from
	heos and machomai, in LXX and here only in the N.T.).
