Esias 51:2

2 Look to Abraam your father, and to Sarrha that bore you: for he was alone when I called him, and blessed him, and loved him, and multiplied him.

Esias 51:2 In-Context

1 Hearken to me, ye that follow after righteousness, and seek the Lord: look to the solid rock, which ye have hewn, and to the hole of the pit which ye have dug.
2 Look to Abraam your father, and to Sarrha that bore you: for he was alone when I called him, and blessed him, and loved him, and multiplied him.
3 And now I will comfort thee, O Sion: and I have comforted all her desert places; and I will make her desert places as a garden, and her western places as the garden of the Lord; they shall find in her gladness and exultation, thanksgiving and the voice of praise.
4 Hear me, hear me, my people; and ye kings, hearken to me: for a law shall proceed from me, and my judgment for a light of the nations.
5 My righteousness speedily draws nigh, and my salvation shall go forth as light, and on mine arm shall the Gentiles trust: the isles shall wait for me, and on mine arm shall they trust.
