This passage has some difficulties that I find fascinating. I'd like to
offer a translation and have the list critique it. Here's the translation:
Concerning the deeds of men, by the word of Your lips I have kept
watch on the path of the robber [NIV: violent] so my feet may cling
to your paths (instead), lest my feet should stumble.
The biggest question that I see has to do with the inf. absolute
TFMOK at the beginning of v.5. BHS suggests reading it as a
qatal 3pl, but doesn't give any ms. justification for the emendation.
I'm thinking it might be a modal of some sort, giving a sense
something like "I'm watching that road to be sure and avoid it."
This, I think, makes sense out of $FMAR:TIY )FRXOWT PFRIYC,
which seems like a rather odd phrase. BHS even suggests moving
the soph pasuq up 2 words so it comes right after $FMAR:TIY, and
I can see why even though I'm not to that point yet.
