Shenayim (H8147) — Two in the Bible
Shenayim (שְׁנַיִם) is the Hebrew dual form meaning 'two,' used as a cardinal number, ordinal ('second'), and to denote a paired unit throughout the Old Testament.
Significado de la palabra
Shenayim (שְׁנַיִם, transliterated shᵉnayim) is the standard Hebrew word for the number two. Morphologically it is a dual form, signaling that Hebrew treats pairs as a natural grammatical category rather than simply as 'one plus one.' The lexicon entry catalogs its range: cardinal 'two,' ordinal 'second,' combinations with other numbers (e.g., 'twelve,' 'twenty'), and the distributive sense 'both.'
The form shifts by gender: with masculine nouns it appears as שְׁנַיִם or שְׁנֵי (Gen 1:16), while with feminine nouns it becomes שְׁתַּיִם or שְׁתֵּי (Gen 4:19; 5:8). This gender-aware inflection is why KJV usage lists both 'twain' and 'two' for the same lemma. It also functions as a building block for higher numbers: שְׁתֵּ֤ים עֶשְׂרֵה ('twelve,' seen in Gen 5:8) literally means 'two-ten.'
Uso en las Escrituras
Shenayim saturates the early pages of Genesis. It counts the sun and moon as the 'two great lights' (Gen 1:16), marks both Adam and Eve as 'both naked... not ashamed' (Gen 2:25), and describes the opened eyes of 'them both' (Gen 3:7). These show the cardinal/collective sense: two individuals forming one unit.
The dual also structures the Flood narrative. Noah is instructed to bring 'two of every sort' onto the ark (Gen 6:19, 6:20), preserving species in pairs, and distinguishing clean from unclean animals by the count 'two' versus 'seven and seven' (Gen 7:2). From civil life (Lamech's 'two wives,' Gen 4:19) to genealogies in chapter 5, where 'nine hundred and twelve years' relies on שְׁתֵּ֤ים as part of the compound for twelve, shenayim is the constant arithmetic backbone of the Hebrew text.

Preguntas frecuentes
Is shenayim just the number two, or does it mean something else?
Its core sense is the cardinal two, but the same form is also used as the ordinal 'second,' as a distributive 'both,' and as a building block for compound numbers like twelve and twenty.
Why does the word look different for men and women in the verse list?
Hebrew numerals inflect by gender. Masculine nouns take שְׁנַיִם or שְׁנֵי (Gen 1:16); feminine nouns take שְׁתַּיִם or שְׁתֵּי (Gen 4:19; 5:8). Both forms belong to the same lemma, H8147.
