In this line, the ver "eqelh|sin" is used, from eqelw. I had great difficulty understanding the form of this verb, until I checked with Autenreith and saw that this verb has a "mi" form when used in the subjunctive, ie, "eqelwmi" !!
How common is it a for a verb to switch from a thematic to an athematic form when changing moods? ( like from indicative to subjunctive )
