"And he made the camels kneel" (Genesis 24:11) - he made them lie down. "At evening time, at the time when the women who draw water come out." Rav Huna said: when a person goes to take a wife and hears the sound of dogs barking, let him listen carefully to what they are saying - "at evening time, at the time when the women who draw water come out."

Yalkut Shimoni on Torah 107:2
(בראשית כד יא) וַיַּבְרֵךְ הַגְּמַלִים, אַרְבָּעִנּוּן. לְעֵת עֶרֶב לְעֵת צֵאת הַשֹּׁאֲבֹת, אָמַר רַב הוּנָא, בְּשָׁעָה שֶׁאָדָם הוֹלֵךְ לִקַּח אִשָּׁה וְשָׁמַע קָל כְּלָבַיָּא מְנַבְּחִין, הוּא צַיִת מַה אִנּוּן אָמְרִין לְעֵת עֶרֶב לְעֵת צֵאת הַשֹּׁאֲבֹת.
