Genesis 16:3

וַתִּקַּ֞ח שָׂרַ֣י אֵֽשֶׁת־אַבְרָ֗ם אֶת־הָגָ֤ר הַמִּצְרִית֙ שִׁפְחָתָ֔הּ מִקֵּץ֙ עֶ֣שֶׂר שָׁנִ֔ים לְשֶׁ֥בֶת אַבְרָ֖ם בְּאֶ֣רֶץ כְּנָ֑עַן וַתִּתֵּ֥ן אֹתָ֛הּ לְאַבְרָ֥ם אִישָׁ֖הּ ל֥וֹ לְאִשָּֽׁה׃

καὶ λαβοῦσα Σάρα ἡ γυνὴ Ἀβρὰμ Ἁγὰρ τὴν Αἰγυπτίαν τὴν ἑαυτῆς παιδίσκην, μετὰ δέκα ἔτη τοῦ οἰκῆσαι Ἀβρὰμ ἐν γῇ Χανάαν, καὶ ἔδωκεν αὐτὴν τῷ Ἀβρὰμ ἀνδρὶ αὐτῆς αὐτῷ γυναῖκα.

Y Sarai, mujer de Abram, tomó á Agar su sierva egipcia, al cabo de diez años que había habitado Abram en la tierra de Canaán, y dióla á Abram su marido por mujer.

So after he had lived in Canaan for ten years, his wife Sarai took her Egyptian maidservant Hagar and gave her to Abram to be his wife.
