They Began to Call By Name

Genesis 4:26

כו וּלְשֵׁת גַּם-הוּא יֻלַּד-בֵּן, וַיִּקְרָא אֶת-שְׁמוֹ אֱנוֹשׁ; אָז הוּחַל, לִקְרֹא בְּשֵׁם יְ-ה-וָ-ה.  {ס}

26 And to Seth, to him also there was born a son; and he called his name Enosh; then began men to call upon the name of the LORD. {S}

Not withstanding Exodus 3:14-15, it says here that people began to use the Tetragrammaton YHWH.  This term of God’s name was in daily use through first Temple times.  By the Second Temple period, it was only said on ritual occasions, such as Yom haKippurim.  Soon, its pronunciation was considered lost.  But it can be reconstructed.  ‘Yahweh’ seems to be the correct pronunciation.

There has been some archeological finds with YHWH, notably “Yahweh and his Asherah“.
