How to combine values ​​with bash from 2 files

I have two files:

text1:

1 element
2 element
3 element
4 element

Text2:

line1
line2
line3
line4
line5
line6
line7

I need to get this result:

1 element at line1
2 element at line2
3 element at line3
4 element at line4
1 element at line5
2 element at line6
3 element at line7

And if I add the five lines of text 1, the expected result is as follows:

1 element at line1
2 element at line2
3 element at line3
4 element at line4
5 element at line5
1 element at line6
2 element at line7
