Revelation 14:1

The 144 Thousands

The Greek ἔχουσαι is the feminine nominative plural present participle of the verb ἔχω in Ancient Greek, which means "to have," "to hold," or "to possess" and it was always a feminine nominative plural. Those who have/hold.

The Greek for 144 thousands is ἑκατὸν τεσσαράκοντα τέσσαρες χιλιάδες and applies to both masculine and feminine since χιλιάδες (thousands) is a feminine noun and not numeral, but numerals themselves are not gender-specific when used with plural nouns like χιλιάδες.

ἑκατὸν τεσσαράκοντα τέσσαρες χιλιάδες translates to "one hundred forty-four thousands," where χιλιάδες functions as the noun for "thousands," and the numerals before it (ἑκατὸν τεσσαράκοντα τέσσαρες) describe how many thousands there are.

Compare xπολλαὶ χιλιάδες ταλάντων many thousands of talents
