<div dir="ltr">When we repeat the pesukim at the end of Hallel, we say the entire pasuk twice, with the exception of the passuk "Ana Hashem Hoshiah Na, Ana Hashem Hatzlichah Na", where we repeat the first half of the pasuk before saying the second half. <div>
<br></div><div>I am aware of the gemara in Arvei Pesachim (119a) that says that the structure of this pasuk is "call and response", ie the second half is a reply to the first, but this is also true of the other pesukim, such as "Baruch Habba Besheim Hashem, Beirachnuchem Mibeis Hashem" which we say in its entirety before repeating.</div>
<div><br></div><div>So why do we say this pasuk differently?</div><div><br></div></div>
