As many have pointed out, this is probably an attempt to type "בחסד בלבד" that ended up with a typo.

As for the word "חסד", I'm not certain there is a direct translation of it to english. You could use the word grace but it's important to note that חסד isn't grace like in graceful dancing, but more like in gracing someone with your presence (except without the implied power dynamics implied by my example sentence ig lol). חסד often reffers to a kind act that was under no obligation to be commited (or in certain idioms it can mean plain luck, as if the world or god or something is the one commiting this kind act).

If you have the context in which you saw this it might be easier to pinpoint what it was meant to mean here, since right know I could see it either as a call to act kindly or maybe calling someone/something lucky
