(7) They have dealt treacherously against the LORD, For they have begotten strange children; Now shall the new moon devour them with their portions.

(3) [Said Raba b. b. Ghana: "Whoever marries a wife who is not fit for him is considered by Scripture as if he plowed the entire world and sowed it with salt ; for it is said (Ib., ib., ib) These were they who came up from Tel-melach, Tel-Charsa." Rabba b. R. Adda said in the name of Rab: "Whoever marries a wife because of her wealth will have degenerate children], as it is said ( Hos. 5, 7) Against the Lord have they dealt treacherously; for strange children have they gotten. You will perhaps think that the money for which such a man married will endure. It is therefore said in the same passage, One month shall devour them together with their possessions. And, if thou wilt think that it refers only to his possessions and not to hers, it is therefore said their possessions. And if you will think that this might take a long time, it is therefore said during one month." How is one month to be understood? Said R. Nachman b. Isaac: "This means literally, that during the time when one month will come and one month will go their wealth will be lost." Raba b. R. Adda said further, and according to others R. Salla said it in the name of R. Hanmuna: "Whoever marries a wife that is not suitable for him, Elijah binds him and the Holy One, praised be He, flogs him." We are taught in a Baraitha: On every case above mentioned Elijah writes and the Holy One, praised be He, affixes His signature to the following: "Woe unto him who disqualified his children and who discredited the reputation of his family through marrying a wife who is not fit." And whoever disqualifies others is a disqualified person and he does not speak on the praiseworthy side of the world. Samuel adds: "That in whatever thing he disqualifies others, from the very same thing comes his own disqualification."

Since he won't be able to tell his lineage, so when it says תל מלח חרשא it refers to a mute, and not to a mound of salt.

If you marry a woman that is פסול to you for the sake of money, your children will not act properly.

(1) [A man should not marry a women that does not have any kind of inappropriateness. Isserless: Anyone who marries an inappropriate wife for money will bring them children who are not respectable, but aside from that, if there is no inappropriateness on her, rather he just marries her for money, it is allowed.] If someone wants to marry an inappropriate wife, his family members may protest him. If he does not want to be supervised by them, he may make a type of sign such that their offspring will not intermingle with that of his family; and someone who offered a lot of money for him to get married and then took back the offer (even though they got married) he should not hold his wife like a hostage because of this and he should not quarrel with her over her family's property, and someone who does this will not be successful and the relationship will not be a good one because the money that a man takes along with his wife is not appropriate money; and anyone who does this is called someone who "marries for money". Rather, everything that a father or mother in-law gives him should be taken with a good-eye (a full heart) and he will be successful.

Paraphrase: The first statement of the Rema, in the name of the Rivash, expresses the prohibition against marrying a woman who is Pasul for the sake of monetary gain. The second statement of the Rema, in the name of the Orchos Chaim, teaches that delaying one's marriage because of monetary concerns is akin to transgressing a prohibition for the sake of money. The delay of the marriage is prone to cause the man to have sinful thoughts (Hirhurim Ra'im), which itself is a sin. If he delays his marriage in order to gain money, he effectively transgresses a prohibition (of Hirhurim Ra'im) for the sake of monetary gain, and thus he is like one who marries a woman who is Pasul for the sake of monetary gain.

It is אסור for someone to get married to a woman before he sees her because he might find her disgusting and hate her, for the פסוק says "love your neighbor as yourself."
