On the First-day following I was at Friends’ meeting at Amsterdam; where, amongst several sorts of professors that were present, was a doctor from Poland, who for his religion was banished the place he lived in; and being affected with the testimony of truth in the meeting, he came afterwards to have some discourse with me; and after we had been some time together, and I had opened things further to him, he went away very tender and loving. While I was at Amsterdam, I spent much of my time in writing books, papers, or epistles on truth’s behalf. I wrote several epistles from Amsterdam to Friends in England and elsewhere, on several occasions, as the Lord moved me by his Spirit thereunto. I wrote also from thence, “A Warning to the Inhabitants of the City of Oldenburg, which was lately burnt down;” also, “A Warning to the Inhabitants of the City of Hamburg,” both of which were as follows:— “_A Warning to the Magistrates and People of the City of Oldenburg._ “FRIENDS, “Have you not seen and felt the judgments of God upon your city, the Lord sending lightning from heaven that destroyed and burnt it? As I passed through your city on a First-day of the week, which you call your Sabbath, I saw some drinking, and soldiers playing at shuffleboard, and others with their shops open and trading, when they should have been waiting upon God and worshipping him; and your people were light and vain, without any sense of God’s judgments or repentance. O therefore repent, lest the all-seeing God, who sees all your actions and is over all, bring swift judgment upon you in his wrath, fury, and indignation. Repent, and lay aside all manner of evil and wickedness, ungodliness, and unrighteousness; for the day of the Lord will come upon all that do evil, all the workers of iniquity. This mighty day of the Lord will find them all out, and will burn as an oven, and burn up all the proud and wicked, and neither leave them root nor branch.
