QUESTION: When did סלק become a Hebrew root? The only instances of in Tanakh are in Aramaic? Also , is it a possible biliteral cognate of the Hebrew סולם (“ladder”) and סוללה (a device used in siege), both of which facilitate ascent? And also סל (“basket”) can be used to lift somethin. Moreover, it seems that סלסלה (in Mishlei 4:8) means ‘lift it up’ according to ראב”ע , as does סלו לרכב בערבות (Tehilim 68:5). There was a city in trans-Jordan called סלכה. (Deut 3:10). Is it because it was a mountainous region and involved ascent? A סלע is a rock. Is it because it’s a high rock that ascends upward? Is סלעם a type of locust that flew higher than others?
