Tikz：使用相对定位匹配线位置

Question

我正在尝试在正文（摘录自《圣经》）中的某些点之间绘制正交线，并使用tikzmark作为锚点和relative positioning形成线形。我需要对齐两条线的垂直部分（用作文本旁边的方括号），但无法对齐，因为它们基于 s 定义的不同位置tikzmark。我需要将第 7b-10b 节旁边的垂直线与第 2-7a 节旁边的垂直线对齐。我尝试使用该calc函数定义坐标，但没有成功。非常感谢您的帮助。

这是我的 MWE：

    \hin Studied by all who have pleasure in them. \\
\textsuperscript{3} His work is honorable and glorious, \\

\textsuperscript{4} He has made His wonderful works to be remembered; \\
    \hin The LORD is gracious and full of compassion. \\
\textsuperscript{5} He has given food to those who fear Him; \\
    \hin He will ever be mindful of His covenant. \\

    \hin In giving them the heritage of the nations. \\
\textsuperscript{7} The works of His hands are verity and justice;\tikzmark{7a} \\
    \hin All His precepts are sure.\tikzmark{7b} \\
\textsuperscript{8} They stand fast forever and ever, \\

\textsuperscript{9} He has sent redemption to His people; \\
    \hin He has commanded His covenant forever: \\
    \hin \hin \hin Holy and awesome is His name. \\
\textsuperscript{10} The fear of the LORD is the beginning of wisdom; \\
    \hin A good understanding have all those who do \\
    \hin \hin His commandments.\tikzmark{10b} \\

输出如下：

coordinate我建议沿着你的路径添加s。

\draw [gray] ([xshift=2pt, yshift=2pt]pic cs:2) -- ++(4.5,0) coordinate (A) |- ([xshift=2pt, yshift=2pt]pic cs:7a);
\draw [gray] ([xshift=2pt, yshift=2pt]pic cs:7b)coordinate (B) --(A|-B) |- ([xshift=2pt, yshift=2pt]pic cs:10b);
