'Lone' in the Bible

But he himself traveled a day’s journey into the wilderness, and he came and sat down under a juniper tree and asked [God] that he might die. He said, “It is enough; now, O Lord, take my life, for I am no better than my fathers.”

I lie awake and I am like a lone bird on a roof.

Look at Abraham, your father, and Sarah, who gave you birth. When I summoned him, he was a lone individual, but I blessed him and gave him numerous descendants.
