According to Ezekiel 16, who spread his skirt over a naked Jerusalem?

God

Now when I passed by thee, and looked upon thee, behold, thy time was the time of love; and I spread my skirt over thee, and covered thy nakedness: yea, I sware unto thee, and entered into a covenant with thee, saith the Lord GOD, and thou becamest mine. Ezekiel 16:8
