John:13:17
rwp@John:13:17 @{If ye know} (\ei oidate\). Condition of first class assumed as true, \ei\ and present (\oidate\ used as present) active indicative. {If ye do} (\ean poite\). Third-class condition, \ean\ and present active subjunctive, assumed as possible, "if ye keep on doing." Both conditions with the one conclusion coming in between, "happy are ye." Just knowing does not bring happiness nor just occasional doing.
