"اضطرم" - Translation from Arabic to English

It was like Aaron had been striking a match and it was being blown out, striking another one, and it was being blown out, and finally he'd managed to catch enough kindling that the flame actually caught,
‫كأنما كان هارون يشعل عود ثقاب فينطفئ ‫فيشعل غيره، فينطفئ ‫حتّى استطاع جمع ما يكفي من الذرو حتى اضطرم اللهب
