I'm looking at getting this commentary.
I noticed the English version is 10 volumes and the
German original is 15 volumes.
English: https://www.logos.com/product/5790/keil-and-delitzsch-commentary-on-the-old-testament
$120
Deutsche: https://www.logos.com/product/43113/biblischer-kommentar-uber-das-alte-testament
$166
Is the German version more complete? 15 volumes vs 10 and a higher price. It's been a while since I used German as a research language but if there is that much more in it then I will surely consider getting the German edition.
