How to get aleph and beth symbols in similar font?

Question

If aleph, beth, gimel, and daleth are needed in their mathematical meanings (identifiers for cardinality), how can we get them in the same font or at least reasonably similar in style. The following simple approach makes aleph different from the rest in style:

\documentclass{article}
\usepackage{amssymb}
\begin{document}
\[ \aleph \beth \gimel \daleth \]
\end{document}

The aleph is smaller and has thinner strokes:

Apparently the reason is that amssymb does not have aleph. What might be the simplest fix?

Answer 1

There are other font that can be used:

• MnSymbol:

  

• FdSymbol:

  

• TX fonts:

  

• PX fonts:

  

• cjhebrew:

  

OpenType fonts (LuaTeX/XeTeX):

• Latin Modern Math:

Answer 2

If you find a Hebrew font, you can use it; in this example I use the fonts provided by the cjhebrew package.

\documentclass{article}
\usepackage{amsmath}

% from cjhebrew.sty (with scaling added)
\DeclareFontFamily{U}{cjheb}{}
\DeclareFontShape{U}{cjheb}{m}{n}{%
  <-11> s*[1.2] cjhblsm
  <11-> s*[1.2] cjhbltx
}{}
\newcommand{\cjhebfamily}{\fontencoding{U}\fontfamily{cjheb}\selectfont}
\DeclareTextFontCommand{\textcjheb}{\cjhebfamily}

% provide the commands in case amssymb is not loaded
\providecommand{\beth}{}
\providecommand{\gimel}{}
\providecommand{\daleth}{}
% renew the commands
\newcommand{\mathhebrew}[1]{\text{\cjhebfamily#1}}
\renewcommand{\aleph}{\mathhebrew{\char'047}}
\renewcommand{\beth}{\mathhebrew{\char'142}}
\renewcommand{\gimel}{\mathhebrew{\char'147}}
\renewcommand{\daleth}{\mathhebrew{\char'144}}


\begin{document}
$X\aleph \beth \gimel \daleth Y$

\end{document}

Answer 3

You could scale it (1.5x horizontal, 1.1x vertical).

EDITED to work in all math styles (thanks, tohecz), and provided a slight vertical shift and kern for better matching. Lastly, enclosed in a group, so that it works directly in a subscript.

\documentclass{article}
\usepackage{scalerel}
\let\oldaleph\aleph
\def\aleph{{\ThisStyle{\scalebox{1.5}[1.1]{%
  \raisebox{-.2\LMpt}{$\SavedStyle\oldaleph$}}\kern-.2pt}}}
\usepackage{amssymb}
\begin{document}
\[ \aleph \beth \gimel \daleth \]
\[ \scriptstyle \aleph \beth \gimel \daleth \]
\[ \scriptscriptstyle \aleph \beth \gimel \daleth \]
\[X_{\aleph_\aleph}\]
\end{document}

Answer 4

run it with xelatex. unicode-math allows to use single characters from another font:

\documentclass{article}
\usepackage{amssymb}
\usepackage{unicode-math}
\usepackage{libertine}
\setmathfont[range={\beth,\gimel,\daleth,\aleph}]{Linux Libertine O}   
\begin{document}
\Huge
בגדא
$ \aleph \beth \gimel \daleth $
\end{document}
