[If there is both] a fatherless boy and girl want to marry, they should marry off the fatherless girl first and then marry off the fatherless by since a woman's shame is greater than a man's. A fatherless boy that wants to marry, they should rent a house for him, lay out a bed for him, and afterwards marry him off to a wife, as it said, "Enough for whatever he lacks, לו" (Devarim 15:8): לו is a wife, as it is said there: "I will make לו, a helper for him" (Bereishit 2:18)—just as לו said there is a wife, so too לו said here is a wife. (The derash is you first give him whatever he lacks monetarily, then give him a wife based on the order of the verse).
