To learn the Indian language had not occurred to him as part of his preparation, but probably these Kent Red men had been enough among the English to understand him, for they seem to have been much impressed.
A Scottish Society for propagating Christian Knowledge had arisen, and the delegates hearing of the zeal of David Brainerd, desired to engage him at a salary.

The sense of his own unworthiness, and fear of keeping out a better man, brought his spirits down to the lowest ebb; nevertheless, he went to meet the representatives of the Society at New York, and there, though between the hubbub of the town and his own perpetual self-condemnation he was continually wretched, they were so well satisfied with him as to give him the appointment, on condition that he studied the language, intending to send him to the Red men between the Susquehanna and the Delaware; but there was a dispute between these and the Government, and it was decided to send him to a settlement called Kanaumeek, between Stockbridge and Albany.
Before going, David Brainerd, having no thought beyond devotion to the Indians, and thinking his allowance enough for his wants, gave up the whole of his inheritance to support a scholar at the University, and set forth, undaunted by such weakness of health as in ordinary eyes would have fitted him for nothing but to be carefully nursed; for even then he was continually suffering from pain and dizziness, and weakness so great that he could often hardly stand.
In this state he arrived at Kanaumeek, with a young Indian to act as his interpreter, and there spent the first night sleeping on a heap of straw.
It was a lonely, melancholy spot, where the Indians were herded together, watched with jealous eyes by adventurers who were always endeavouring to seize their lands, and sadly degenerated from the free, grave, high-spirited men to whom Eliot had preached.

His first lodging was in the log house of a poor Scotchman who lived among the Indians--a single chamber, without so much as a floor, and where he shared the family meals upon porridge, boiled corn, and girdle-cakes.

The family spoke Gaelic, only the master of the house knowing any English, and that not so good as the Indian interpreter's; and, moreover, the spot was a mile and a half from the Indian wigwams, no small consideration to so weakly a man, thus poorly fed.

However, the Indians were pleased with his addresses, and seemed touched by them; but the evil habits of the White men were the terrible stumbling-block.
