Jewish and Christian numbering systems are different for The Bible. If you mean Psalm 51:10, it doesn't appear to contain the word steadfast in Jewish translations (Jewish numbering system):
Make me to hear joy and gladness; that the bones which Thou hast crushed may rejoice.
תַּשְ×מִיעֵ×?Ö´×™ שָׂשׂוֹן וְשִׂמְחָה תָּגֵלְ×?ָה עֲצָמוֹת דִּכִּיתָ׃
But Psalm 51:12 does:
Create me a clean heart, O God; and renew a stedfast spirit within me.
לֵב טָהוֹר ×‘Ö°Ö¼×¨Ö¸× ×œÖ´×™ ×Ö±×œÖ¹×”Ö´×™× ×•Ö°×¨×•Ö¼×—Ö· ×?ָכוֹן ×—Ö·×“ÖµÖ¼×©× ×‘Ö°Ö¼×§Ö´×¨Ö°×‘Ö´Ö¼×™×ƒ
The word translated as "steadfast" is actually ×?כון which means "correct" or "right".
"Yatziv" (יציב) and "Kavo'a" (קבוע) means Steadfast in Hebrew.
Hebrew does not use symbols. It uses actual letters.The word 'steadfast' in letters is יציב and it is pronounced yatsív
steadfastness = yatsivut
It sounds like you are asking about the Hebrew word Chessed (חסד), which is usuallytranslated as "Lovingkindness" or "Kind love."The phrase in Psalm 118 that is sometimes translated as "steadfast love" is a mistranslation of the Hebrew: Ki le'olam chasdo (כִּ֖י לְעֹולָ֣ם חַסְדֹּֽו) which means "for his love endures forever", (literally "because eternally his kindness"). The only other mentions of "steadfast love" in the Christian Bible come from the New Testament and if the term you are looking for is in there, then it would be in Koine Greek, not Hebrew.
I mean his steadfast courage, his calm continual self-control.
The closest word I can think of is: khesed (חסד) which means "lovingkindness"
Kupa'a means Steadfast, Firm, Immovable, Loyal
Onipa'a means "steadfast" in Hawaiian. It was Queen Liliuokalani's motto.

I Went in a steadfast way
The antonym of steadfast is disloyal
Luis doesn't mean anything in Hebrew. Only Hebrew names have meaning in Hebrew.
