וַיְהִי-עֶרֶב וַיְהִי-בֹקֶר יוֹם שְׁלִישִׁי.

وَكَانَ مَسَاءٌ وَكَانَ صَبَاحٌ يَوْمًا ثَالِثًا.

Y fué la tarde y la mañana el día tercero.

And the evening and the morning were the third day.

Moses 2:13
And the evening and the morning were the third day.

Abraham 4:13
And it came to pass that they numbered the days; from the evening until the morning they called night; and it came to pass, from the morning until the evening they called day; and it was the third time.

Notes/Questions:

I’m not sure why the Spanish (Reina Valera 1909) says “tarde” (which usually translates into English as “afternoon”) instead of “noche” … or maybe there’s another Spanish word for evening that could be used.

Abraham 4:13 refers to this as “the third time” - which leaves plenty of room for the idea that in these verses the word “day” is merely a word used to describe distinct periods of time - periods of time that may or may not be equal in duration.
