Oh, baby! Jill Duggar welcomed her son with husband Derick Dillard on Monday, and on Tuesday's installment of "19 Kids and Counting," the TLC reality stars discussed their baby's name.

In the episode, titled “Jill’s Having A…,” the new mom -- who was just 17 weeks pregnant in the pre-taped episode -- was waiting to learn her child’s gender. Ahead of hosting a gender reveal party for her family, Jill and Derick revealed their baby name picks.

“We do have names picked out for a boy and a girl,” Derick, 25, revealed as Jill, 23, looked on smiling. “If it’s a boy, we’re going to name his Israel, which means ‘God will prevail.’”

As most “19 Kids and Counting” viewers are aware, the duo did welcome a son Monday night and granted him the name Israel David. The newest member of the Duggar family weighed in at a whopping 9 lbs., 10 ounces, at birth.

While not much has been shared regarding Jill and Derick's reason for choosing their baby boy's name, the couple did announce what their girl name would have been on “19 Kids and Counting” Tuesday. “If it’s a girl, we’re going to name her Selah, which means ‘pause and reflect,’” Derick revealed.

After the expectant parents and a select few members of the Duggar family attended a gender-determining ultrasound, the Duggars and the Dillards learned that Jill would be having a boy. The big reveal happened by way of blue-colored candy inside of a piñata.

"It's really exciting to know that we are having a little baby boy," Derick said after the announcement. "There is just something about a father-son connection. Being the first-born son myself, and having that connection with my dad, it will be really neat to pass on that legacy to my first-born son."

Jill later addressed her son by his name during a phone conservation with her sister-in-law, Anna Duggar. “We’re so thrilled," she said. "So, little Israel is his name."

Immediately following the episode's premiere, TLC released a televised statement about Jill and Derick's new arrival. “Congratulations to Jill and Derick on the birth of their son,” said the announcement, which included a photo of the couple holding up pairs of pink and blue baby shoes. “Welcome the newest member of the TLC family, baby Israel David Dillard.”
