Apparently, this is the inspiration behind Kim Kardashian and Kanye West’s son’s name

"On that level, the baby name isn’t a surprise.”

A week after welcoming their fourth child, Kim Kardashian and Kanye West announced their son's name last night [May 18] - and it was definitely unique. The Keeping Up With the Kardashians star announced on Instagram that they had decided to name their baby boy Psalm. Now, a source close to the proud dad-of-four has revealed the inspiration behind the name of the newest member of the Kardashian-West family. They told PEOPLE:

“Kanye is very involved in choosing the names. He and Kim do exactly what every couple does, where they each bring up names and the other one gives their feedback. "It’s very traditional that way. Kanye would never just choose a name that Kim doesn’t like, or vice versa. The names are things that they mutually agree upon.”

They added that Psalm is a "good reflection" of where the couple were spiritually. The insider added:

“I know that both of them read the Bible regularly now. Kanye loves the Books of Poetry of the Bible: Job, Psalms, Proverbs, Ecclesiastes, Song of Solomon. He reads them over and over. “Psalms is the longest book in the Bible, but Kanye believes that there’s a lot of wisdom in them.”

They also said that the newborn's name "isn't a surprise,' as Kanye "really identifies" with King David. The source continued:

“David was a mess, always falling into sin and messing up, but the Bible says he was a ‘man after God’s own heart.’ Kanye loves that. “He reads the Psalms a lot. He talks about the Psalms he loves. So on that level, the baby name isn’t a surprise.”
