1. In the harmony of her disposition. Husband and wife should be like the image in a looking-glass, that answers in all properties to the face that stands before it; or like an echo, that returneth the voice it receiveth. Many marriages are like putting new wine into old bottles. An old man is not a meet-help for a young woman: He that sets a grey head upon green shoulders, hath one foot in the grave and another in the cradle: Yet, how many times do you see the spring of youth wedded to the winter of old age?--A young man is not a meet-help for an old woman; raw flesh is but an ill plaister for rotten bones. He that in his non-age marries another in her dotage, his lust hath one wife in possession, but his love another in reversion. 2. In heraldry of her condition. Some of our European nations are so strict in their junctions, that it is against their laws for the commonality to couple with the gentry. It was well said by one, “If the wife be too much above her husband, she either ruins him by her vast expenses, or reviles him with her base reproaches; if she be too much below her husband, either her former condition makes her too generous, or her present mutation makes her too imperious.”--Marriages are styled matches, yet amongst those many that are married, how few are there that are matched! Husbands and wives are like locks and keys, that rather break than open, except the wards be answerable. 3. In the holiness of her religion. If adultery may seperate a marriage contracted, idolatry may hinder a marriage not perfected. Cattle of divers kinds were not to ingender. 2 Cor. vi. 14. _Be not unequally yoked, &c._ It is dangerous taking her for a wife, who will not take God for a husband. It is not meet that one flesh should be of two spirits. Is there never a tree thou likest in the garden but that which bears forbidden fruit? There are but two channels in which the remaining streams shall run:--1. To those men that want wives, how to choose them. 2. To those women who have husbands, how to use them.
