Apparently they knew how to program in bible (partial translation of a traditional passover song below):

If He had brought us out from Egypt,
and had not carried out judgments against them
— Dayenu, it would have sufficed!
If He had carried out judgments against them,
and not against their idols
— Dayenu, it would have sufficed!
If He had destroyed their idols,
and had not smitten their first-born
— Dayenu, it would have sufficed!
If He had smitten their first-born,
and had not given us their wealth
— Dayenu, it would have sufficed!
If He had given us their wealth,
and had not split the sea for us
— Dayenu, it would have sufficed!
If He had split the sea for us,
and had not taken us through it on dry land
— Dayenu, it would have sufficed!
