פּירוש אויף תהילים 78:63

Fire consumed his youths [The fire of] His wrath.

were not married Heb. לא הוללו. They were not married by being brought into a litter [under] a canopy because the youths died in battle.

הוּלָלוּ is an expression of nuptials (הִלוּלָא) in Aramaic. Our Sages, however, explained it in reference to Nadab and Abihu (Mid. Ps. 78:18), but I feel uncertain about explaining it that way because he already commenced with the Tabernacle of Shiloh.
