From a makeshift stage near the Gaza border, hostage families used giant speakers to call out to their captive family members Thursday morning.
The families had traveled down to Israel's south to speak to their loved ones in a convoy that left Tel Aviv on Wednesday.
Over 300 cars and thousands of people were included in the convoy, and Israelis waited to show their support at various locations around the country, according to the Hostage Family Forum.
"It's mama," said Rachel Goldberg-Polin, speaking into the microphone to her son Hersh.
"Hersh we are working day and night and we will never stop," she said.
"It's day 328," Goldberg-Polin told her son. "We are all here - all the families of the remaining 107 hostages."
She also told him that she wants him to know that she continues to give him a blessing every Friday evening, and every morning.
Ella Ben Ami, whose mother Raz was released in the November hostage deal and whose father Ohad is still held hostage, called out to her father that she is taking care of her mother.
"We are taking care of her every day. She came back from there and so will you, dad, we are not giving up."
"Ohad Ben Ami," she yelled into the microphone. "Can you hear me?"
"I miss you. I will do anything, anything to hug you again. Ohad Ben Ami, hold on! Don't break!"
'I will not give up'
Yehuda Cohen, father of hostage Nimrod Cohen, also spoke to his son across the border.
"Nimrod Cohen, dad is talking to you, we are here next to the Gaza border to tell you that we are continuing to fight for you. I will not give up until you come home, I will continue to run everywhere in the world until we make a deal that will free you and all the hostages."
Varda Ben Baruch, the grandmother of American-Israeli hostage Edan Alexander, who was abducted after he came to Israel to serve in the IDF as a lone soldier, told Edan that they love him and are waiting for him.
"Be strong, you are a strong guy. Take care of yourself, survive. We love you."
After calling out to their loved ones, the hostage families rushed towards the border with Gaza before being stopped by security forces.
