No way to find Hebrew words used in the NT Greek?

[Carmen Thomas-Comeaux]

BLB does Hebrew to English, Greek to English, Greek to Hebrew, but not Hebrew to Greek?? If I want to know when the same word as H3427 is used anywhere in the Bible, not just the OT, but including in the New Testament Greek and Aramaic language, there isn't an easy way? For Greek to Hebrew, it's easy, just hit the LXX link. But is there ANY way similar to do the reverse? Like one Hebrew word (H5401) can mean kiss, to equip, to fasten. How do I find every time H5401 shows up in the NT? And is there a way to get the verses that mean kiss in the Septuagint? Each time H5401 shows up as equip in the Septuagint? Each time H5401 shows up as fasten in the Septuagint? I have googled, YouTubed, asked my pastor. No one has knowledge of a database that easily links the Hebrew words to words in the other languages in the Bible? This can't be true in a time of supercomputers and AI. I can study the Hebrew and Septuagint physically side by side, but that is so time intensive and doesn't offer the lists of all verses. I can't be the only one-has anyone found anyway with the BLB or any other resource?

Thank you for your responses even though I don't see them here, only in my emails for some reason.  I have thought of this, but it since is possible through the Septuagint to know for example, that the first time the word for "sat" in Rev 6:2 occurs is in Gen 18:1 with Abraham sitting in the tent opening, a connection between the 2 verses has been established.  Why can't we look at the link from both directions? Maybe I'm not understanding something fundamental. But I was able to make the connection for "sat." It just took a number of steps. In hermeneutics, I thought the rule of first mention of a word or concept was often kind of important to establishing a starting place for understanding the fullness of the word or concept.
