What posuk for the name Golda is to be said at the end of Shemoneh Esrei?
I spell it with an aleph at the end and the Artscroll siddur doesn't have the gimmel, aleph combination.
Here is a Posuk that starts with a Gimel and ends with an Aleph
איוב פרק-יג-ט"ז גַּם הוּא לִי לִישׁוּעָה כִּי לֹא לְפָנָיו חָנֵף יָבוֹא
Here is a nifty website where you can look up Pesukim that begin with a letter you desire and end with a letter you desire. There are some names that have a combo that does not exist. See here for what one can do in such an instance.
Following correct Yiddish orthography, 'Golda', in Hebrew letters, should be spelled with an 'א' at the end. This doesn't leave too many options for verses beginning & ending with those letters. No verses given in prayer books are mandated; they are suggestions which have become popular over the centuries. Job 13:16 is one possible option:
גַּם-הוּא-לִי לִישׁוּעָה: כִּי-לֹא לְפָנָיו, חָנֵף יָבוֹא.
