While he was thus employed in Scotland, he received letters from the English congregation at Geneva, stating that they had made choice of him as one of their pastors, and urging him to come and take the inspection of them.[277] He judged it his duty to comply with this invitation, and began immediately to prepare for the journey. His wife and mother‑in‑law had by this time joined him at Edinburgh; and Mrs Bowes, being now a widow, resolved to accompany Mrs Knox and her husband to Geneva. Having sent them before him in a vessel to Dieppe, Knox again visited and took his leave of the brethren in the different places where he had preached. He was conducted, by his friend Campbell of Kineancleuch, to the earl of Argyle, and preached for some days at {188} his seat of Castle Campbell.[278] That aged nobleman appears to have received durable impressions from the instructions of the Reformer. He resisted all the arts which the clergy afterwards employed to detach him from the protestant interest, and on his death‑bed laid a solemn charge upon his son to use his utmost influence for its preservation and advancement. Argyle, and Glenorchy, who was also a hearer of Knox, endeavoured to detain him in Scotland, but without success. “If God so blessed their small beginnings,” he said, “that they continued in godliness, whensoever they pleased to command him, they should find him obedient. But once he must needs visit that little flock, which the wickedness of men had compelled him to leave.” Accordingly, in the month of July 1556, he left Scotland, and having joined his family at Dieppe, proceeded along with them to Geneva.[279]
