§ Of the Return of the Noldor The Silmarillion

Angrod son of Finarfin was the first of the Exiles to come to Menegroth, as messenger of his brother Finrod, and he spoke long with the King, telling him of the deeds of the Noldor in the north, and of their numbers, and of the ordering of their force; but being true, and wisehearted, and thinking all griefs now forgiven, he spoke no word concerning the kinslaying, nor of the manner of the exile of the Noldor and the oath of Fëanor. King Thingol hearkened to the words of Angrod; and ere he went he said to him: 'Thus shall you speak for me to those that sent you. In Hithlum the Noldor have leave to dwell, and in the highlands of Dorthonion, and in the lands east of Doriath that are empty and wild; but elsewhere there are many of my people, and I would not have them restrained of their freedom, still less ousted from their homes. Beware therefore how you princes of the West bear yourselves; for I am the Lord of Beleriand, and all who seek to dwell there shall hear my word. Into Doriath none shall come to abide but only such as I call as guests, or who seek me in great need.'
